A 35-177 mum Tunable Intersubband Emitter for the Far-Infrared

Abstract

Under the influence of a perpendicular electric field the mini-bands of a superlattice break up and from localised electron states within each quantum well. The energy separation between adjacent well states is proportional to the field and the system has become known as a Stark Ladder. This work investigates the potential of superlattices within the Stark Ladder regime as tunable intersubband emitters for the far-infrared region of the spectrum.
