Theory and measurements of harmonic generation in semiconductor superlattices with applications in the 100 GHz to 1 THz range

Pereira, M. F. ; Zubelli, J. P. ; Winge, D. LU ; Wacker, Andreas LU orcid ; Rodrigues, A. S. ; Anfertev, V. and Vaks, V. (2017) In Physical Review B 96(4).
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 gigahertz to terahertz applications.
