Hierarchical Device Simulation (eBook, PDF)

The Monte-Carlo Perspective

• Format: PDF

Produktbeschreibung

This monograph is the first on physics-based simulations of novel strained Si and SiGe devices. It provides an in-depth description of the full-band monte-carlo method for SiGe and discusses the common theoretical background of the drift-diffusion, hydrodynamic and Monte-Carlo models and their synergy.
