Monte Carlo Analysis of Anisotropy in the Transport Relaxation Times for the Hydrodynamic Model

Abstract

This paper investigates the anisotropy properties of the relaxation times used in the hydrodynamic model. To this purpose a calculation of the collision term of the Boltzmann Transport Equation is performed by means of a Monte Carlo code accounting for the proper band structure and scattering features. Numerical results for electrons in silicon are shown at 77 and 300 K for E ║ <100> and E ║ <111>.
