 b. Reporting of Inventions. The Institute shall report each Subject Invention to the Sponsor as soon as possible after becoming aware of the
conception or reduction to practice thereof 
  
 c. Filing of
Applications. 
  
 1. The Institute shall retain
title to each Institute Subject Invention. As to each such Institute Subject Invention, Sponsor can request Institute to file a patent application and Institute agrees to do so provided Sponsor covers the cost of filing and maintaining the patent
application, patents issuing therefrom and foreign counterparts, if any. The Institute shall have the right thereafter to elect whether of not it will file a patent application covering Subject Invention. Patent applications relating to such Subject
Invention(s) shall be filed by the Institute in its name. 
  
 2. Joint Subject Inventions shall be jointly owned by Institute and Sponsor. Patent applications relating to a Subject Invention made jointly by Institute personnel and other persons participating in the work
supported by this Agreement shall be filed as mutually agreed by the parties, at Sponsor’s expense unless Sponsor has not initiated the filing of such patent applications, and Institute and Sponsor shall together select independent patent
counsel satisfactory to both parties to prepare and prosecute any such applications. Patent applications relating to Joint Subject Inventions shall be filed in the names of Institute and the Sponsor. 
  
 3. Subject Inventions made solely by person(s) who are not
Institute personnel shall be owned by Sponsor provided such personnel do not first actually reduce to practice a Subject Invention shall be a Joint Subject Invention as defined above. Patent applications owned by Sponsor shall be filed by Sponsor.

 4. As regards 13.c.1 and 13.c.2., both parties shall have the right to review and comment
upon applications and correspondence with the Patent Office and shall be provided with drafts thereof sufficiently in advance to reasonably allow for such review and comment. 
  
 5. Institute agrees that it will cause to be signed by concerned Institute personnel all documents necessary
to obtain patent as set forth above, and that Institute will do whatever Sponsor reasonably requests to obtain and maintain such patent rights, at the expense of Sponsor. 
  
 6. If Sponsor is not interested in having a patent application filed with respect to a particular Subject
Invention made solely by Institute personnel or jointly, Sponsor shall advise Institute of such fact within sixty (60) days from the date the Subject Invention was disclosed to Sponsor by Institute, or sooner if necessary to avoid loss of patent
rights. Institute may then at its own expense, file and prosecute such patent application, and patent application and any patents issuing therefrom shall not be included within the rights licensed to Sponsor pursuant to this Agreement, and Institute
shall be free to license its rights in such patent to any party. 
  
 d. Licenses. 
  
 1. For any Subject
Invention for which Institute has any right, Sponsor shall receive a nonexclusive, royalty-free, irrevocable license to use the invention covered by the license for its own internal purposes. However, such a nonexclusive license will not include the
right to sublicense and is nontransferable, except in the event of the transfer or sale of all or substantially all of Sponsor’s assets to a third party. 
  

2. Sponsor shall have the option to acquire, upon mutually agreeable terms, a royalty bearing, exclusive or nonexclusive, world-wide
license in the Field, including the right to sublicense, to make, have made, use, lease and sell products embodying or produce through the use of any Subject Invention. Said option must be exercised by written notice to Institute within six (6)
months after receiving from Institute written notice of the filing of a patent application. If Sponsor elects to exercise its option to acquire a license on mutually agreeable terms within the prescribed time period, both parties agree to negotiate
license terms in good faith but not to exceed 2%. All such negotiations including the execution of a license agreement shall be completed within six (6) months of written notice to Institute of Sponsor’s exercise of said option. If Sponsor
fails to agree to terms waived said option, and the Institute shall be free to license a third party; provided, however, that for a period of three (3) years after written notice of Sponsor’s exercise of its option to Subject Invention(s), the
Institute shall not agree to license a third party on more favorable terms than were offered to Sponsor without first offering Sponsor a license on those more favorable terms and providing Sponsor with ninety (90) days in which to accept such offer.
If Sponsor fails to notify Institute within the ninety (90) days that is has accepted such terms, Sponsor shall be deemed to have rejected the offer, and Institute shall, thereafter, be free to license its rights in the Subject Invention(s) to other
parties. If Sponsor notifies Institute within ninety (90) days that it accepts such an offer, Institute shall be deemed to have entered into a binding license agreement with respect to such terms. 

 3. Any license granted to Sponsor pursuant to paragraph l3.d.2. shall be subject to the
California Institute of Technology Patent Policy and Institute’s prior agreements with other sponsors and shall provide: (a) for a reasonable royalty on net sales of products utilizing the licensed technology to be paid to the Institute; (b)
for Institute to retain a nonexclusive license, with the right to grant sublicenses, for research purposes only; (c) if and to the extent applicable to the licensed Subject Invention, that the rights of the Unites States of America as set forth in
Public Laws 96-517 and 98-620 (codified at 35 U.S.C. 200 et seq.) are especially reserved, and that Sponsor shall comply with the provision of 35 U.S.C. 204, as amended from time to time; and (d) that nothing contained in this clause shall imply a
license to the Sponsor under any patent, patent application or other invention other than a Subject Invention as defined herein.

 OUTLINE OF RESEARCH OBJECTIVES AND
PLAN OF WORK FOR 
  
 The goal of my research program is to
investigate, exploit and manipulate novel phenomena that emerge in nano-scaled materials. In particular, this program aims to identify and understand new transport phenomena in nano-scaled systems, to create devices such as memories and logic gates
that operate on new principles, and to find new ways to control and detect the motion of matter on the nanometer scale. 
  
 The study of matter that is patterned on the nanometer length scale is an exciting and fascinating frontier of science. The behavior of ultra-small
objects often differ in remarkable ways from their bulk counterparts, and can lead to surprising new phenomena differing sharply from what might be expected by simply considering scaled-down versions of the laws governing bulk matter. Investigating
the properties of nanometer scaled matter thus leads to the observation of new phenomena and requires new concepts to understand them, comprising a rich and dynamic facet of the scientific enterprise. In turn, this new understanding promises to
provide a coherent and unified understanding of the disparate fields of condensed-matter physics, biology and chemistry. 
  
 Aside from yielding such fundamental knowledge, the manipulation and control of matter at the nanometer length scale promises to have a wide variety of
technological applications. These applications range from nano-scale optoelectronic components to chemical and biological sensors and electronic circuits. In particular, the area of information technology promises to benefit greatly from the
enhanced device speed and integration density afforded by nanometer scale devices. However, we must understand the new transport phenomena that emerge in nano-scale materials in order to enable the rational design of devices such as memory elements
and logic gates. This research area comprises the burgeoning field of nanoelectronics, a sub-field of nano-scaled technology that generated a great deal of excitement. We will fabricate these devices using a combination of “bottom-up”
chemical or biological synthesis and “top-down” conventional lithographic techniques, comprising a variety of materials ranging from carbon nanotubes to individual molecules, and we will perform a variety of transport and scanned-probe
experiments to elucidate and exploit their properties. An example of this technique is shown in Fig. I, which shows an AFM image of a multi-walled nanotube incorporated into a field-effect transistor geometry. 
  
 Moreover, we will fabricate devices with novel principles of operation based
on the interplay between the electronic and mechanical degrees of freedom of nanometer scale objects. In the simplest case these devices may yield faster and more compact versions of conventional micro-electromechanical (MEMS) devices. More
importantly, for sufficiently small structures, novel electromechanical properties emerge, in analogy to the new electronic properties that emerge in nanoelectronic systems. Ultimately, from these devices we will endeavor to both develop novel
approaches to controlling and detecting the motion of matter at the nanometer scale and exploit new physical phenomena to create nanoscale devices with unique functionality. Examples of such nanoelectromechanical devices could potentially include
ultra-small resonators, oscillators, and mixers operating at microwave frequencies. 
  
 Indeed, the revolutionary possibilities afforded by gaining control and understanding of the 

 behavior of matter at nanometer length scales seem nearly limitless. Our research group aims to create a synergistic
enterprise to explore, understand, and exploit this abundantly fertile area with the goal of producing a wealth of novel and useful devices and concepts. 
  
 DELIVERABLES TO ARROWHEAD RESEARCH 
  
 The deliverables will consist of a technical report supplied to Arrowhead Research at each anniversary of the start date of this research agreement. Each technical report
will include details of scientific progress and results covered by the work outlined in the research agreement, as well as highlighting specifically those results that may be of possible commercial interest to Arrowhead Research. In addition, at the
end of each year, Bockrath agrees to submit a follow-on Statement of Work, mutually agreeable to both parties, that will reflect any changes in research goals or that identifies new opportunities that both Bockrath and Arrowhead Research wish to
pursue. Caltech will also provide reprints of any publications in scientific journals resulting from the work outlined in the research agreement. In addition, brief (one page), non-technical reports on our research progress, intended for a general
audience including stockholders of Arrowhead Research, will be supplied on request. 
  
 BUDGET JUSTIFICATION 
  
 Budget Request Summary:
The PI is requesting a total dollar amount of $810,351 for the full five year period of the research agreement with Arrowhead Research. The amount of$162,070 per year includes direct costs such as salaries and benefits for two graduate and
undergraduate students, administrative support, domestic travel, and supplies and expenses, and indirect costs, at the Indirect Cost Rate of 62%. 
  
 Salaries: The salaries of two full-time graduate students, at $22,000 per person per year, will be supported by this research agreement. In addition,
graduate students require tuition costs of $13,970 per person per year. An amount for administrative support of $l0,000 along with $2,650 in fringe benefits is also requested. 
  
 Supplies and Expenses: The requested amount of $15,000 per year for routine supplies and expenses is based on an estimate of
$7,500 per person per year. These funds will be used to purchase items such as helium gas and liquid, glassware, silicon and silicon-nitride AFM tips, machine shop, electrical shop and glass shop charges, computers, monitors and printers. The funds
also estimate yearly charges from the microfabrication user facility in the Applied Physics Department and the TEM facility in the Materials Science Department at Caltech. 
  
 Equipment: An amount of $5000 is requested to acquire a computer along with specialized hardware to perform transport
measurements. 
  
 Domestic Travel: Funds of $3060 per year will be
used to pay for expenses incurred for three conference visits to meetings such as (but not limited to) the American Chemical Society, the American Physical Society, and Gordon Research Conferences. These funds cover travel expenses, conference fees
and lodging.

Subject Invention. As to each such Institute Subject Invention, Sponsor can request Institute to file a patent application and Institute agrees to do so provided Sponsor covers the cost of filing and maintaining the patent application, patents
issuing therefrom and foreign counterparts, if any. The Institute shall have the right thereafter to elect whether of not it will file a patent application covering Subject Invention. Patent applications relating to such Subject Invention(s) shall
be filed by the Institute in its name. 
  
 2.
Joint Subject Inventions shall be jointly owned by Institute and Sponsor. Patent applications relating to a Subject Invention made jointly by Institute personnel and other persons participating in the work supported by this Agreement shall be filed
as mutually agreed by the parties, at Sponsor’s expense unless Sponsor has not initiated the filing of such patent applications, and Institute and Sponsor shall together select independent patent counsel satisfactory to both parties to prepare
and prosecute any such applications. Patent applications relating to Joint Subject Inventions shall be filed in the names of Institute and the Sponsor. 
  
 3. Subject Inventions made solely by person(s) who are not Institute personnel shall be owned by Sponsor provided such personnel do not
first actually reduce to practice a Subject Invention shall be a Joint Subject Invention as defined above. Patent applications owned by Sponsor shall be filed by Sponsor. 
  
 4. As regards 13.c.1 and 13.c.2., both parties shall have the right to review and comment upon applications
and correspondence with the Patent Office and shall be provided with drafts thereof sufficiently in advance to reasonably allow for such review and comment. 
  
 5. Institute agrees that it will cause to be signed by concerned Institute personnel all documents necessary to obtain patent as
set forth above, and that Institute will do whatever Sponsor reasonably requests to obtain and maintain such patent rights, at the expense of Sponsor. 
  
 6. If Sponsor is not interested in having a patent application filed with respect to a particular Subject Invention made solely by
Institute personnel or jointly, Sponsor shall advise Institute of such fact within sixty (60) days from the date the Subject Invention was disclosed to Sponsor by Institute, or sooner if necessary to avoid loss of patent rights. Institute may then
at its own expense, file and prosecute such patent application, and patent application and any patents 

  

 
issuing therefrom shall not be included within the rights licensed to Sponsor pursuant to this Agreement, and Institute shall be free to license its rights
in such patent to any party. 
  
 d. Licenses. 

 
 1. For any Subject Invention for which Institute has any
right, Sponsor shall receive a nonexclusive, royalty-free, irrevocable license to use the invention covered by the license for its own internal purposes. However, such a nonexclusive license will not include the right to sublicense and is
nontransferable, except in the event of the transfer or sale of all or substantially all of Sponsor’s assets to a third party. 
  
 2. Sponsor shall have the option to acquire, upon mutually agreeable terms, a royalty bearing, exclusive or nonexclusive, world-wide
license in the Field, including the right to sublicense, to make, have made, use, lease and sell products embodying or produce through the use of any Subject Invention. Said option must be exercised by written notice to Institute within six (6)
months after receiving from Institute written notice of the filing of a patent application. If Sponsor elects to exercise its option to acquire a license on mutually agreeable terms within the prescribed time period, both parties agree to negotiate
license terms in good faith but not to exceed 2%. All such negotiations including the execution of a license agreement shall be completed within six (6) months of written notice to Institute of Sponsor’s exercise of said option. If Sponsor
fails to agree to terms waived said option, and the Institute shall be free to license a third party; provided, however, that for a period of three (3) years after written notice of Sponsor’s exercise of its option to Subject Invention(s), the
Institute shall not agree to license a third party on more favorable terms than were offered to Sponsor without first offering Sponsor a license on those more favorable terms and providing Sponsor with ninety (90) days in which to accept such offer.
If Sponsor fails to notify Institute within the ninety (90) days that is has accepted such terms, Sponsor shall be deemed to have rejected the offer, and Institute shall, thereafter, be free to license its rights in the Subject Invention(s) to other
parties. If Sponsor notifies Institute within ninety (90) days that it accepts such an offer, Institute shall be deemed to have entered into a binding license agreement with respect to such terms. 
  
 3. Any license granted to Sponsor pursuant to paragraph
l3.d.2. shall be subject to the California Institute of Technology Patent Policy and Institute’s prior agreements with other sponsors and shall provide: (a) for a reasonable royalty on net sales of products utilizing the licensed technology to
be paid to the Institute; (b) for Institute to retain a nonexclusive license, with the right to grant sublicenses, for research purposes only; (c) if and to the extent applicable to the licensed Subject Invention, that the rights of the Unites
States of America as set forth in Public Laws 96-517 and 98-620 (codified at 35 U.S.C. 200 et seq.) are especially reserved, and that Sponsor shall comply with the provision of 35 U.S.C. 204, as amended from time to time; and (d) that nothing
contained in this clause shall imply a license to the Sponsor under any patent, patent application or other invention other than a Subject Invention as defined herein. 
  
 e. Government Rights. Under certain circumstances, it is possible that the research may be supported in part by one
or more agencies of the U.S. Government. If this should occur, the reporting of inventions or discoveries and the disposition of title to patent applications or patents resulting therefrom will be subject to the terms and conditions of the
Institute’s contractual agreement with any such agency or agencies. If such a circumstance develops and if the Sponsor desires to acquire rights, the Institute agrees to make every possible effort to acquire title to such inventions and to
offer the Sponsor the option for acquisition of rights as outlined in the preceding paragraph, subject to the prior rights of, or conditions imposed thereon by, the U.S. Government. 
  

 14. CONFIDENTIALITY OF SPONSOR’S INFORMATION. Sponsor may wish, from time to time, in connection
with work contemplated under this Agreement, to disclose confidential information to Institute personnel. To protect the confidentiality of such information, Sponsor may request the Principal Investigator, who has the right to refuse to accept such
information, to sign a confidentiality agreement with Sponsor, in the form of Exhibit 2 hereto. Such a request shall not extend to other research personnel. Institute will not be responsible for any failure of individual performance under such
confidentiality agreement.

 High performance micro- and nano-electromechanical 
 materials and devices in ferroelectric thin films

 We propose a four-year- research program which will exploit new ferroelectric film synthesis capabilities developed recently in the Atwater Group to make
thin film piezoelectric devices with very high work output that are suitable for integration into microelectromechanical devices on silicon substrates. The work will focus on: 
  

	 	•	Growth of high quality biaxially-textured ferroelectric thin films on biaxially-textured MgO templates deposited on amorphous films on Si.

  

	 	•	Synthesis of single-crystal ferroelectric thin films via wafer bonding and layer transfer techniques. 

  

	 	•	Fabrication of high performance piezoelectric microelectromechanical devices in biaxially-textured ferroelectric thin films and single-crystal
ferroelectric thin films. 

  
 Until now,
ferroelectric thin films have been widely explored for applications as capacitor dielectrics and memory elements in non-volatile random access memory devices, but much less effort has been devoted to applications in microelectromechanical systems
(MEMS). This is in part due to poor quality of thin film materials that have been available for MEMS actuators. In most cases, the ferroelectric thin films had polycrystalline microstructures that degrade domain switching, and piezoeleotric
coefficients and also result in time-dependent fatigue, which has adversely affected device reliability. 
  
 We have recently identified two broad synthetic strategies that have promise for high work/volume piezoelectric actuators in micro-electromechanical
systems (MEMS) applications. First is growth of biaxially-textured ferroelectric thin films that have potential to create piezoelectric devices that approach the quality of single crystal devices at modest cost. Second is the
fabrication of single crystal ferroelectric thin films for devices by wafer bonding and layer transfer techniques, which has yielded, for the first time, ferroelectric thin films whose properties are as good as those of bulk
materials and whose mechanical reliability is superior to that of bulk crystals. Both of these approaches exploit 90° domain switching which has the potential for “high strain ferroelectric” devices with very high
work/volume and reasonable cycling frequencies, as compared with other technologies for MEMS devices. A comparison of the work output of high strain ferroelectrics with other device technologies is given in Fig. 1. 
  
 Biaxially-textured ferroelectric film growth. The biaxially-textured ferroelectric
film growth process enables greater process flexibility and latitude for MEMS integration on silicon since integration of MEMS rnicroactuator devices can be achieved during or after the “back end” 

  

 
of a silicon integrated circuit process, i.e. after the silicon electronic devices and interconnects have been fabricated and protected from contamination by
deposition of amorphous dielectric overcoat layers. This route for ferroelectric/silicon integration uses very thin (~ 10 nm) biaxially textured MgO films as epitaxial templates for ferroelectric film growth. Biaxially textured materials are
highly-oriented polycrystalline films with a narrow range of in-plane and out-of-plane crystallographic orientations. We have also demonstrated epitaxy of BaTiO3 and PbTiO3 on biaxially-textured MgO templates. The out-of-plane
orientation was defined by [001]ferroelectric parallel to [001]MgO and the in-plane orientation by [001]ferroelectric parallel to [100]MgO. Biaxially textured MgO films were grown on amorphous Si3N4/Si substrates using ion beam-assisted deposition (IBAD. The MgO biaxial texture was controlled by varying the ion/MgO molecule flux ratio during deposition. The IBAD MgO film is either directly used as a heteroepitaxial template for
PBT or was first coated with a 20 nm layer of homoepitaxial MgO grown at 600° C. Molecular beam epitaxy (MBE) will be used to grow BaxPb1-xTiO3
co-evaporation of Pb (99.999% pure) and Ba (99% pure) from effusion cells, and Ti from a Varian Ti-ball sublimation source. The oxygen source is an Oxford Applied Research HD25 RF
atom source with O2 introduced into the back of the source. The RF atom source has an O2-to-atomic-O cracking efficiency of 30% at 500W. 
  
 Ferroelectric films via layer transfer fabrication. Layer transfer fabrication is one of the most promising methods to realize single
crystal properties in thin films, and to overcome substrate-film lattice mismatch effects. Crystal ion slicing processes have been reported for layer transfer of silicon, InP, Ge and diamond. Recently, we have successfully employed this technology
for layer splitting and transfer of the ferroelectric materials LiNbO3 and BaTiO3. We transferred single crystal BaTiO3 (400 nm thick) films onto Pt-coated Si and Si3N4/Si substrates by ion implantation-induced layer transfer used H+/He+ ion co-implantation and subsequent heat treatment. The
transferred BaTiO3 films are single crystalline with surface RMS roughness of 17 nm. Polarized optical and
piezoresponse force microscopy (see Fig. 2) indicated that — remarkably— BaTiO3 film domain structure
closely resembles that of bulk BaTiO3 and clearly shows 90o a-c domain structure with tetragonal angle of.0.5~0.6°. Micro-Raman spectroscopy indicated that local vibrational modes in the ion implanted
BaTiO3 layer fully recovered during the transfer process annealed above Curie temperature and the transferred layer
shows typical single crystal tetragonal BaTiO3 structure. From the piezoresponse force microscopy, the piezoelectric
constant, d33, value is found to be 80-100 pm/V and the coercive electric field (Ec) is 12-20 kV/cm, values
almost identical to those seen in single crystal BaTiO3. These results imply that now ferroeleotric thin films can be made with properties rivaling those of bulk crystals. 
  
 Device Fabrication. The proposed program will apply the film synthesis techniques described above to make simple piezoelectric thin film devices using facilities
in the Atwater lab and also the Micro/Nano Fabrication Lab, a newly created laboratory for microfabrication and nanofabrication located on the first floor of Watson Laboratory at Caltech. These laboratories have conventional optical lithography with
a 1.5 μm resolution mask aligner suitable for up to 3” substrates, positive photoresist processing, wet chemical etching, CVD for silicon nitride and silicon dioxide, metal evaporation, polymer layer fabrication, optical inspection and
metal thin film evaporation. Device characterization by I-V, C-V, Hall mobility and carrier density and spreading resistance can be performed from 25-150 C. An electrical measurement probe station 

  

 
is available for current-voltage and capacitance voltage characterization using Keithley Instruments ICS-based 236 source-measurement units. Surface
profilometry and piezoresponse force microscopy is available using a Thermomicroscope AutoProbe CF atomic force microscope.
