Growth of InAs/GaSb short-period superlattices for high-resolution mid-wavelength infrared focal plane array detectors
M Walther,J. Schmitz,R. Rehm,S. Kopta,Frank Fuchs,Joachim Fleißner,Wolfgang A. Cabanski,Johann Ziegler +7 more
TL;DR: In this article, the InAs/GaSb short-period superlattices (SLs) with a broken gap type-II band alignment are investigated for the fabrication of photovoltaic pin-photodetectors on GaSb substrates.
