Abstract :
This paper aims at comparing the pseudospectral method and discrete geometric approach for modeling quantization effects in nanoscale devices. To this purpose, we implemented a simulation tool, based on both methods, to solve a self-consistent Schrödinger-Poisson coupled problem for a 2-D electron carrier confinement according to the effective mass approximation model (suitable for FinFETs and nanowire FETs).
