Investigation of Charge Trapping at Grain Boundaries in Polycrystalline and Multicrystalline Silicon Solar Cells
Authors: Heath Jennifer T. , Jiang Chun-Sheng , Moutinho Helio , Al-Jassim Mowafak 
Published: August 2010

AbstractScanning capacitance microscopy (SCM) often shows a change in contrast at grain boundaries [1-3]. The origins of this contrast and the efficacy of SCM as a tool to identify band bending at grain boundaries in pc-Si and mc-Si are discussed. Contrast at these grain boundaries could be influenced by different oxide growth rates or by defect states at the oxide interface. In order to determine the influence of such mechanisms on the SCM signal, such effects must be modeled; we show that a simple one-dimensional model agrees well with more detailed models of SCM signal strength and indicates, for example, that very small changes in oxide thickness measurably affect the SCM signal. In our experimental data, the uniformity and quality of the oxide layer are confirmed, and increased contrast consistent with depletion regions is still observed at higher order grain boundaries as identified by electron backscattering diffraction, including 9 and 27a. Scans of the SCM signal as a function of dc probe voltage allow such regions to be more quantitatively investigated.

Published: August 2010

AbstractIn this study, we use novel thermal deposition techniques to synthesize films of poly(vinlyidene fluoride), or PVDF, containing nanoparticles of the ceramic titanium dioxide (TiO2). This ferroelectric polymer has shown promise as a capacitor dielectric material, and possible enhanced electrical properties when combined with ceramic nanoparticles. Characterization of these composite films has been performed including chemical structure and microstructure using SFM, XPS, and EDS techniques. Measurements of film parameters such as dielectric constant and breakdown voltage have also been performed, and the dispersion of the ceramic particles within the films has been characterized

Published: August 2010

AbstractThe objective of this research is to obtain uniform vacuum-deposition triclinic phase II crystal of titanyl phthalocyanine (α-TiOPc) films from various TiOPc crystal forms. The crystal structure and morphology of vacuum-deposited TiOPc films can be manipulated by deposition rate and substrate temperature. Crystal structure was determined by X-ray diffraction (XRD). Thin film morphology was analyzed by scanning electron microscope (SEM). Highly ordered α-TiOPc film with an edge-on molecular orientation was deposited on octadecyltrichlorosilane (OTS) treated Si/SiO2 surface. All TiOPc crystal forms, such as amorphous, α and γ phases, provided the triclinic phase II crystal of TiOPc. The full width at half maximum (FWHM) of the peak at 7.5 degree in XRD spectra was 0.23, 0.27 and 0.29 for γ, α and amorphous powder when substrate temperature maintained at 180°C, respectively. The FWHM of the 7.5 degree peak can be achieved 0.22 deposited from all crystal forms at elevated temperature higher than 220°C. The α-TiOPc deposition film exhibited an excellent p-type semiconducting behavior in air with dense packing structure due to the close π–π molecular packing. The devices, field-effect mobility range from 0.02 to 0.26 cm2/V s depending on various process parameters. The on/off current ratio (Ion/Ioff) is over 105. The TiOPc OTFTs will be applied as multi-parameter gas sensor in the near future.

Published: August 2010

AbstractIn this paper we investigate the energetic alignment in an organic p-i-n homojunction using ultraviolet photoelectron spectroscopy. The device is made of pentacene and we emploay the small molecules NDN1 for n-doping and NDP2 for p-doping the layers. The full p-i-n structure is deposited stepwise on a silver substrate to learn about the interface dipoles and band bending effects present in the device. From the change in work function between the p- and n-doped layers we gain knowledge of the built-in potential of this junction.
Rolled-up helical nanobelts: from fabrication to swimming microrobots
Authors: Zhang Li , Nelson Bradley J. 
Published: August 2010

AbstractWe present recent developments in rolled-up helical nanobelts in which helical structures are fabricated by the self-scrolling technique. Nanorobotic manipulation results show that these structures are highly flexible and mechanically stable. Inspired by the helical-shaped flagella of motile bacteria, such as E. coli, artificial bacterial flagella (ABFs) are a new type of swimming microrobot. Experimental investigation shows that the motion, force, and torque generated by an ABF can be precisely controlled using a low-strength, rotating magnetic field. These miniaturized helical swimming microrobots can be used as magnetically driven wireless manipulators for manipulation of microobjects in fluid and for target drug delivery.

Published: August 2010

AbstractRapid development in the area of low-temperature fuel cells has led to increased attention on catalyst synthesis with cost effective and environmentally-benign technology (green chemistry). In this study, a highly dispersed palladium nanoparticle catalyst was successfully prepared on a bacterial cell support by a single-step, room-temperature microbial method without dispersing agents. The metal ion reducing bacterium Shewanella oneidensis were able to reduce palladium ions into insoluble palladium at room temperature when formate was provided as the electron donor. The prepared biomass-supported palladium nanoparticles were characterized for their catalytic activity as anodes in polymer electric membrane fuel cell for power production. The maximum power generation of the biomass-supported palladium catalyst was up to 90% of that of a commercial palladium catalyst.

Authors: Li Shaofan , Zeng Xiaowei 
Published: August 2010

AbstractIn this paper, we briefly report our recent work on multiscale modeling and simulations of soft elasticity and focal adhesion of stem cells. In particular, our work is focused on modeling and simulation of contact and adhesion of stem cells on substrates with different rigidities. In order to understand the precise mechanical influences on cell contact/adhesion and to explain the possible mechanotransduction mechanism, we have developed a three-dimensional soft-matter cell model that uses liquid-crystal gel or liquid-crystal elastomer gel to model the overall constitutive relations of the cell, and we have simulated the responses of the cell to extra-cellular stimulus. The discussion here is specifically focused on the following issues: (1) how to model the overall myosin responses at the early stage of differentiation process of the stem cell, (2) the effects of both the adhesive force due to ligand-receptor interaction or focal adhesion and the surface tension, and (3) possible cell conformation and configuration changes triggered by substrate's rigidity.

Authors: Braccini Muriel L , Perrin Bertrand R.M. , Bidan Cécile , Dupeux Michel 
Published: August 2010

AbstractThe practical adhesion of equine pericardium membranes bonded with surgical glue has been measured by the bulge-and-blister technique under injection of pressurized distilled water. The value of the interfacial crack propagation energy can be estimated from the critical debonding pressure. The measured practical adhesion energies are weak with regards to those of engineering structural adhesives, but they are reliable enough to allow a comparison between different surgical glues and a study of the influence of the bonding experimental conditions.
66.4: Surface Polarity Controlled Horizontal Chevron Defect Free Surface Stabilized Ferroelectric Liquid Crystal Devices
Authors: Lin Chi‐Wen , Hsu Chih‐I , Chen Huang‐Ming Philip 
Published: August 2010

AbstractThe asymmetrical surface polarity controlled hybrid alignment technique was proposed to suppress the alignment defects of half V‐shaped switching FLC materials. When the material was cooled from N* to SmC*, two kinds of layer arrangements were formed with opposite spontaneous polarization directions (Ps). Alignment layers with opposite surface polarity direction were utilized in asymmetrical hybrid cells and produced uni‐surface‐polarity direction. FLC Ps was only controlled by this surface polarity; therefore, double domains were suppressed into mono‐domain. A 2.4” prototype TFT‐LCD was presented with defect‐free alignment texture. This alignment technique provided promising FLC material with well alignment and fast switching for TFT‐LCD application.

The delay time of the output pulse of gate driver circuits with different layout characteristics was analyzed by a distributed‐load modeling. The effect of TFT properties, clock phase and the output load on the optimum condition is given. Finally, scaling has been found to give apparent power law dependence on the circuit area, signifying higher performance of the circuits with smaller area.

Published: August 2010

AbstractWe introduce a new way to characterize auto‐stereoscopic 3D displays using multi‐location viewing angle measurements and calculation of 3D properties in the observer space. We show that a measurement with a very high angular resolution and low parasitic light is needed. A new Fourier optics instrument dedicated to this application is introduced that exhibits a practical angular resolution better than 0.03° for an aperture angle of 50° and a very low level of parasitic light. The specific problem of geometric compensation of 3D displays is examined using multi‐locations measurements from different displays.

Published: August 2010

AbstractLTPS TFT backplane for Large Scale AMOLED Device was fabricated using a new special Joule‐Heating Induced Crystallizing (JIC) method. A mass production compatible process for large scale AMOLED Product was newly developed using JIC method. By adopting the new process architecture, additional conducting layer was removed and additional processes were dramatically reduced for mass production. In addition, laser tool or long‐time furnace annealing process was removed in LTPS process. Poly‐Si showed a wide range of crystallinity by changing processing parameters and the p channel TFTs of this work exhibited a mobility of up to 25.4 cm2/V⋅sec, threshold voltage of −1.5V, sub‐threshold slope of 0.67 V/dec, and on/off ratio of 4 × 104. We believe that this technology can be successfully applied to the mass production of large scale AMOLED TV.

Published: August 2010

AbstractLocal dimming of backlights achieves high contrast ratio and low power consumption for LCDs. However, it induces flicker artifacts. The moving average filtering method effectively reduces the flicker artifacts, but causes another problem known as backlight‐response‐time delaying. This paper presents an adaptive moving average filtering method to deal with above problems. Experimental results show that the proposed method successfully reduces flickers without backlight‐response‐time‐delaying.

Published: August 2010

AbstractRecently, a single phase driving method has been adopted for driving CCFL lamps to provide a low cost implementation. However, high voltage driving signals are coupled to pixel electrodes through parasitic capacitance between the lamps and panel electrodes, generating artifacts in the display. This paper describes the analysis results of this phenomenon and the proposed automatic delay compensation scheme eliminates the artifacts caused by the coupling effect.

Published: August 2010

AbstractWe used a resist‐assisted patterning (RAP) process for the growth of CNTs as electron emitters. The electron emission sites were easily controlled by simple resist patterning process. To obtain stabilized and enhanced electron emission, post growth treatment process was adopted. The electron emission current strongly depended on the post growth treatment conditions. The electron emission current was increased with increasing acid treatment time up to 20 second. The enhanced electron emission current was more enhanced with consecutive post growth temperature and acid treatment. After 20 sec post growth treatment on robust CNTs, we can obtain 1.62 mA/cm2 current density at 4 V/μm field. The controlled electron emission current of CNT emitter array with RAP process and structural improvement of CNT‐FEAs after HF treatment for enhanced electron emission was discussed.

P‐71: Spectrum Relaxation Applied to Film‐Thickness Measurement
Authors: Yang Fu‐Shiang , Chen Hsin‐Yi , Chiang Chih‐Jung 
Published: August 2010

AbstractWhen we used spectrometer with array sensor to calculate thickness or control refractive index, spectrum resolution was the important factor if we measured the reflectance or transmittance as our first step. This situation would be emphasized while the testing sample was the super thick film (>20 μm) which caused the large dense reflectance or transmittance spectrum. In this paper, we developed a method to improve the measurable range of film thickness by use of the different incident angle spectrum. It means the spectrum obtained from thick film would become sparser even we used the same hardware. Some concrete examples would be described here and their results would be shown in this paper.

Authors: Mphepö Wallen , Huang Yi‐Pai , Shieh Han‐Ping D. , Rudquist Per 
Published: August 2010

AbstractUsing well established concepts from thin film optics we hereby present a forward looking new design for a high performance display system. The system design is centered around the selective reflections and transmissions of well defined and constructed thin films. By computing the relevant parameters for specific thin films that can reflect and transmit only Red, Green and Blue light and marrying the result to an RGB LED backlight system a rather unique display system emerges. This display system does away with almost all the other familiar components in Flat Panel Displays as we know them today. This is due to the fact that the resulting systems uses no Color Filters, no Polarizers, no Color Wheel, no Phosphors and last but not least no Liquid Crystal Material either. The impact of by passing these display staples is a drastically increased Optical Efficiency and Color Saturation orders of magnitude higher.
