    Abstract

    This manuscript describes harmonic generation in semiconductor superlattices, starting from a Nonequilibrium Green's functions input to relaxation rate-type analytical approximations for the Boltzmann Equation in which imperfections in the structure lead to asymmetric current flow and scattering processes under forward and reverse bias. The resulting current-voltage curves and the predicted consequences on harmonic generation, notably the development of even harmonics are in good agreement with experiments. Significant output for frequencies close to 1 THz (7th harmonic) at room temperature, after excitation by a 141 GHz input signal, demonstrate the potential of superlattice devices for GHz-THz applications.
