Abstract
Previously, GaAs/AlAs superlattices with a small active area (~1 μm2) were used by us to design mixer diodes. It was established that these superlattices can efficiently be used in the terahertz (THz) range. It was theoretically and experimentally shown that short-period (i.e., containing few periods) superlattices in the composition of harmonic mixers have significant advantages in comparison with multi-period (with 50–100 or more periods) superlattices at frequencies of up to 5.3 THz. In this study, the superlattice design is optimized and the operation efficiency of short-period superlattices is shown to be determined to a large extent by the transition regions located at the superlattice edges.
