Internal photoemission from quantum well heterojunction superlattices by phononless free-carrier absorption
Creators
Abstract
The possibility of phononless free-carrier absorption in quantum well heterojunction superlattices was investigated. Order of magnitude calculation showed that the absorption coefficient was significantly enhanced over the phonon-assisted process. Important aspects of the enhancement in the design of infrared photodetectors are discussed.
