abstract = "Semiconductor superlattice frequency multipliers have emerged as a nonlinear medium able to generate radiation in a wide frequency range. This property facilitates the potential of sources suitable for sensing and spectroscopy applications. In this study, we further investigate the consequences on harmonic generation in a superlattice multiplier after excitation by an input signal oscillating at different frequencies. Here we provide a rigorous description of our theoretical model including a semiclassical Boltzmann approach to nonlinear miniband transport and non-equilibrium Green{\textquoteright}s functions calculations treating scattering processes under forward and reverse bias. To fully exploit the features of this radiation source, we focus on the effects of elastic scattering and systematic imperfections in the superlattice structure which lead to asymmetric current flow.",
