We show that with a Full-Band dispersion, the specific heat is closer to the experimental value than with an isotropic quadratic dispersion. So we use a Full-Band dispersion in the transport algorithm. A Monte Carlo algorithm has been developed to simulate phonon transport in silicon nanowire. It has been successfully used to simulate the thermal conductivity.
In this work we present a theoretical study of the effect of random alloy fluctuations in a InGaN inclusion embedded in a GaN nanowire (NW) LED on the electronic and optoelectronic properties. The calculations are based on an empirical tight-binding (ETB) model, while strain is calculated with a valence force field (VFF) method. Energy gaps distributions are obtained and an optical spectral broadening...
This work focuses on studying band-to-band tunneling in 3D devices, while considering variations in material properties (mass, doping), applied bias, or geometry. A simulation study of cylindrical nanowires, tapered structures and doping concentration variation demonstrates the importance of 3D effects in band-to-band tunneling current computation.
