Analog ICs simulations using space charge waves in two-valley semiconductor films

Analog ICs simulations using space charge waves in two-valley semiconductor for microwave and millimeter range signal processing is presented. The formulation incorporates the full set of Maxwell´s equations and the equations of motion of carriers based on a two-valley fully specified model providing a quantitative description of the space charge waves in thin-film n-GaAs. Numerical solutions to the system of equations indicate that the propagation and amplification of space charge waves in the thin film for four signals with different frequencies is possible. The present formulation can also find application where we need to know the interaction of electromagnetic waves and charge carriers.
