Simulation of magnetotransport in nanoscale devices

Abstract

The Boltzmann equation is solved by a spherical harmonics expansion including a magnetic force perpendicular to the two-dimensional simulation plane in real space. The new approach is used to verify a methodology for extracting the electron minority mobility of SiGe HBTs. Magnetotransport in a silicon n+nn+ device is simulated and a strong impact of the maximum number of spherical harmonics on the simulation result is found.
