Wigner ensemble Monte Carlo simulation without splitting error of a GaAs resonant tunneling diode

Wigner Ensemble Monte Carlo: Challenges of 2D Nano-Device Simulation

We announce a two dimensional WIgner ENSemble (WIENS) approach for simulation of carrier transport in nanometer semiconductor devices. The approach is based on a stochastic model, where the quantum character of the carrier transport is taken into account by generation and recombination of positive and negative particles. The first applications of the approach are discussed with an emphasis on t...

Monte Carlo Simulation of Gaas(001) Homoepitaxy

By carrying out Monte Carlo simulations based on the two-species atomic-scale kinetic growth model of GaAs(001) homoepitaxy and comparing the results with scanning tunneling microscope images, we show that initial growing islands undergo the structural transformation before adopting the proper β2(2 × 4) reconstruction. In developing optoelectronic devices, GaAs(001) is often used as the basis s...

Extended Ensemble Monte Carlo

" Extended Ensemble Monte Carlo " is a generic term that indicates a set of algorithms which are now being popular in a variety of fields in physics and statistical information processing. Exchange Monte Carlo (Metropolis-Coupled Chain, Parallel Tempering), Simulated Tempering (Expanded Ensemble Monte Carlo), and Multicanonical Monte Carlo (Adaptive Umbrella Sampling) are typical members of thi...
