Electroless Deposition of W‐doped Ag Dendrites from HF Solution
Authors: YE Wei‐Chun , MA Chuan‐Li , CHANG Yan‐Long , WANG Chun‐Ming 
Published: August 2008

AbstractA simple method was developed for the preparation of W‐doped Ag dendrites by using electroless deposition from hydrofluoride solution. The samples characterized by XPS, XRD, SEM and TEM techniques, show that the growth of silver is leading and can not be changed essentially by tungstate ions in the Ag‐W binary system. A doping mode of W element was proposed, i.e., the doping of W may occur during silver deposition through chemisorption‐chemical bonding of oxygen atoms of tungstate dimer with silver. Cyclic voltammetry was employed to determine the chemical bonding energy between silver and oxygen.
Homolytic Bond Dissociation Enthalpies of C–C and C–H Bonds in Highly Crowded Alkanes
Authors: ZHU Chen , RUI Lei , FU Yao 
Published: August 2008

AbstractThe homolytic C–C and C–H bond dissociation enthalpyies (BDE) of highly crowded alkanes were calculated by using an ONIOM‐G3B3 method. Geometric parameters such as bond length, bond angle and molecular volume were carefully investigated, as most of the acyclic alkanes in this study were not yet synthesized. These parameters reflect the influence of steric effect on BDE. Good correlations were found between the rapid decrease of BDE and the increase of molecular volumes. The correlations can be applied to the prediction of the possible existence of many highly strained compounds.
Benzene‐1,3,5‐tricarboxylate‐bridged Double‐layered Nickel(II) Complex with Ferromagnetically Coupled Ni3 Units
Authors: YANG Hui‐Juan , CUI Ai‐Li , WANG Ru‐Ji , KOU Hui‐Zhong 
Published: August 2008

AbstractThe reaction of benzene‐1,3,5‐tricarboxylic acid (H3BTC) with NiCO3 under hydrothermal conditions afforded a new 2D complex Ni3(BTC)2(µ‐H2O)2·6H2O, which possesses an infinite double‐layered structure. The layer is comprised of syn‐syn carboxylate‐ and aqua oxygen‐bridged Ni3 units that are connected further by BTC3−. Ferromagnetic exchange interaction is operative between the Ni2+ ions, experimentally showing the propagation of ferromagnetic coupling through the syn‐syn carboxylate bridges because the magnetic exchange through the aqua bridges [Ni–O–Ni bond angle=122.8(3) °] is antiferromagnetic. On the basis of the present results and the previous reports on syn‐syn carboxylate‐bridged Ni(II) complexes, it was found that the coplanarity of Ni–O–C–O–Ni dominated the magnetism. The planar arrangement of Ni–O–C–O–Ni gives rise to strong antiferromagnetic coupling, whereas the deviation from planarity weakens the antiferromagnetic coupling, possibly resulting in weak ferromagnetic coupling. Therefore, similarly to the mixed ligand‐bridged Cu(II) dimer the orbital complementary effect (OCE) is also operative in the aqua‐/carboxylate‐bridged Ni(II) dimer.

The CVD of Nanodiamond Materials
Authors: Butler James E. , Sumant Anirudha V. 
Published: August 2008

AbstractThe growth and characteristics of nanocrystalline diamond thin films with thicknesses from 20 nm to less than 5 µm are reviewed. These materials contain between 95% and >99.9% diamond crystallites, the balance being made up from other forms of carbon. Within this class of materials there is a continuous range of composition, characteristics, and properties which depend on the nucleation and growth conditions. It is convenient to classify these films as either ultra‐nanocrystalline‐diamond (UNCD) or nanocrystalline‐diamond (NCD) based on their microstructure, properties, and growth environment. In general, UNCD materials are composed of small particles of diamond ca. 2–5 nm in size with sp2‐carbon bonding between the particles. UNCD is usually grown in argon‐rich, hydrogen‐poor CVD environments, and may contain up to 95–98% sp3‐bonded carbon. NCD materials start with high density nucleation, initiating nanometer‐sized diamond domains which grow in a columnar manner with the grain size coarsening with thickness. NCD is generally grown in carbon‐lean and hydrogen‐rich environments. NCD and UNCD exhibit an interesting range of physical properties which find use in X‐ray windows and lithography, micro‐ and nanomechanical and optical resonators, tribological shaft seals and atomic force microscopy (AFM) probes, electron field emitters, platforms for chemical and DNA sensing, and many other applications.
Quantum Transport in Boron‐Doped Nanocrystalline Diamond
Authors: Mareš Jiří J. , Hubík Pavel , Krištofik Jozef , Kindl Dobroslav , Nesládek Miloš 
Published: August 2008

AbstractHighly grained thin films of boron‐doped diamond are grown by plasma‐enhanced (PE)CVD. Diamond nucleation surface treatment is discussed, together with its relation to the morphology, topology, and phase composition of the layers. The influence of the random incorporation of boron atoms in a diamond lattice is described in terms of Mott's metal and the weak localization (WL) transport mechanism. Starting from these concepts and from the experimental transport data, we build up a simple original theory of the superconductivity in boron‐doped diamond that is based on a spinflip pairing mechanism. We analyze an influence of the grain boundaries in nanocrystalline diamond (NCD) on superconductivity‐related quantum transport phenomena, and show a decisive role of the weak links created by point contacts between grains.
Investigation on Nanodiamond and Carbon Nanotube‐Diamond Nanocomposite Synthesized using RF‐PECVD

Published: August 2008

AbstractNanodiamond (ND) and carbon nanotube‐diamond (CNTD) nanocomposite films are synthesized on silicon(100) substrates, discharging hydrogen‐based gas mixture (methane and hydrogen), using radio frequency plasma‐enhanced (RF‐PE)CVD. Substrate pretreatment conditions are examined for enhancing microdiamond (MD), ND, CNTD nanocomposite, or carbon nanotube (CNT) nucleation. Well‐faceted MD with a low nucleation density, on a silicon substrate, is achieved using a solution of NaOH in water to roughen the silicon substrate, while ND, CNTD nanocomposite, and CNTs are acquired using Co(NO3)2/Mg(NO3)2.6H2O or Fe(NO3)3.9H2O/Mg(NO3)2.6H2O or Ni(NO3)2.6H2O/Mg(NO3)2.6H2O solution in alcohol dripped onto the silicon substrate, which means that pretreatments have a significant influence on grain size, nucleation density, and microstructure of the obtained films. The growth mechanisms for ND and CNTD nanocomposite are discussed.
The Impact of Diamond Grain Size on Hydrogen Concentration, Bonding Configuration, and Electron Emission Properties of Polycrystalline‐Diamond Films
Authors: Michaelson Shaul , Ternyak Orna , Akhvlediani Rozalia , Hoffman Alon 
Published: August 2008

AbstractIn the present work we review our recent studies of the incorporation of hydrogen and its bonding configuration in diamond films composed of diamond grains of varying size. Polycrystalline‐diamond films are deposited by three different methods; hot filament (HF), microwave (MW) and direct current glow discharge (DCGD)CVD. The size of the diamond grains which constitute the films varies in the following way; hundreds of nanometers in the case of HFCVD (“sub‐micrometer size”, ∼300 nm), tens of nanometers in the case of MWCVD (3–30 nm), and a few nanometers in the case of DCGDCVD (“ultra nanocrystalline diamond”, ∼5 nm). Raman spectroscopy (RS), secondary ion mass spectroscopy (SIMS), and high‐resolution electron energy loss spectroscopy (HREELS) are applied to investigate the hydrogen trapping in the films. The hydrogen retention of the diamond films increases with decreasing grain size, indicating the likelihood that hydrogen is bonded and trapped in grain boundaries, as well as on the internal grain surfaces. RS and HREELS analyses show that at least part of this hydrogen is bonded to sp2‐ and sp3‐hybridized carbon, thus giving rise to typical CH vibration modes. Both vibrational spectroscopies show the increase of sp2 CH modes in transition from sub‐micrometer to ultra nanocrystalline grain size. The impact of diamond grain size on the shape of the RS and HREELS hydrogenated diamond spectra is discussed. In addition, the dependence of electron emission properties on film thickness and diamond grain size is reported.
Growth of Diamond Nanoplatelets by CVD
Authors: Chen Hou‐Guang , Chang Li , Cho Shih‐Yin , Yan Jhih‐Kun , Lu Chun‐An 
Published: August 2008

AbstractHexagonal, single‐crystalline, diamond nanoplatelets synthesized by microwave plasma (MP)CVD on Au‐Ge alloy and nanocrystalline diamond (nc‐diamond) film substrates, respectively, are reported. On the nc‐diamond matrix, hexagonal diamond nanoplatelets can grow to a thickness of as little as approximately 10 nm. The effects of various processing parameters, such as methane concentration, microwave power, and gas pressure, on the growth of diamond nanoplatelets are explored. High‐resolution transmission electron microscopy (HRTEM) reveals that the diamond nanoplatelets contain multi‐parallel twins, and the side faces of the platelets exhibit {100}/{111} ridge‐and‐trough structure. Anisotropic growth of diamond nanoplatelet is believed to result from the side face structure of the twinned platelets and intensive plasma reaction.
Nanodiamond‐Coated Carbon Nanotubes: Early Stage of the CVD Growth Process
Authors: Orlanducci Silvia , Tamburri Emanuela , Terranova Maria Letizia , Rossi Marco 
Published: August 2008

AbstractA series of deposits formed by single‐walled carbon nanotube (SWNT) bundles coated by nanocrystalline diamond (NCD) are produced using a modified CVD reactor. The nanocylindrical structures are deposited on Si substrates using carbon nanopowders and atomic H as reactants. The nanocrystalline coating obtained from short‐time runs lasting up to 6 min are analyzed by micro‐Raman and cathodoluminescence (CL) techniques, in order to obtain information on the structural evolution of the material during the first steps of the growth process. The morphological investigation performed by field emission scanning electron microscopy (FESEM) indicates that the nanocrystalline coating generated by a process lasting 4–6 min is formed by protruding embryo diamond crystallites with a needle‐like shape. Thereafter the shape of the diamond phase evolves giving rise to elongated and better faceted diamond grains well anchored on the nanotube bundle surfaces.
Molecular Dynamics Simulations of the Sticking and Etch Behavior of Various Growth Species of (Ultra)Nanocrystalline Diamond Films
Authors: Eckert Maxie , Neyts Erik , Bogaerts Annemie 
Published: August 2008

AbstractThe reaction behavior of species that may affect the growth of ultrananocrystalline and nanocrystalline diamond ((U)NCD) films is investigated by means of molecular dynamics simulations. Impacts of CHx (x= 0– 4), C2Hx (x = 0 – 6), C3Hx (x = 0 – 2), C4Hx (x = 0 – 2), H, and H2 on clean and hydrogenated diamond (100)2 × 1 and (111)1 × 1 surfaces at two different substrate temperatures are simulated. We find that the different bonding structures of the two surfaces cause different temperature effects on the sticking efficiency. These results predict a temperature‐dependent ratio of diamond (100) and (111) growth. Furthermore, predictions of which are the most important hydrocarbon species for (U)NCD growth are made.
