Transport properties under current stress are examined for a carbon nanofiber (CNF) on an insulating substrate between tungsten-deposited gold electrodes. The temperature dependence of CNF resistance is determined based on our previously reported heat transport model. The measured devices exhibit a thermal activation behavior, suggesting transport in a disordered medium. The extracted activatio...

the kinetics and mechanism of the reaction of 5-nitro-1h-benzo[d] imidazole to produce 6-nitro-1h-benzo[d] imidazole was studied by employing hybrid meta-density functional theory. mpwblk/6-31+g** level calculations were carried out to obtain energies and optimize the geometries of all stationary points along the pes, and determine the harmonic vibrational frequencies. two transition states (ts...

The paper presents a model developed for numerical simulation of temperature dependence of a hypothetical Si and SiC diode and BJT current-voltage characteristics. A classical Si PN wide-base diode model and an E-M BJT model are used with SiC semiconductor-specific parameters. Intrinsic carrier concentrations, carrier mobility temperature and doping concentration dependence are calculated for b...
