Tunable terahertz oscillations in superlattices subject to an in-plane magnetic field

TL;DR

This paper introduces a novel method for generating tunable terahertz oscillations in superlattices using crossed in-plane magnetic and electric fields, differing from traditional Bloch oscillations.

Contribution

It presents a new mechanism for terahertz oscillations in superlattices driven by in-plane magnetic and electric fields, expanding the understanding of field-induced oscillations.

Findings

Terahertz oscillations can be generated under crossed magnetic and electric fields.

The oscillation frequency is tunable via the applied fields.

This method differs from standard Bloch oscillations.

Abstract

We present a concept of terahertz oscillations in superlattices that are generated under conditions apparently different from standard Bloch oscillations. These oscillations are induced when crossed magnetic and electric fields are applied to the superlattice, both in the in-plane direction. The frequency of these oscillations is tunable by the applied fields.
