摘要：

Strain influences the optical properties of group III–V type-II superlattice (T2SL) materials. The performance of T2SL photodetectors containing InAs/GaSb is strongly affected by strain. Therefore, it is important to develop novel T2SL material systems and study the stress conditions between their epitaxial layers. Herein, the effect of strain on the long-wave infrared emission characteristics of InAs/In x Ga 1−x As y Sb 1−y T2SLs on InAs and GaSb substrates was investigated. Free, compressive, and tensile strains were adjusted by precisely ...
