Optical properties of GaInAs/AlInAs single quantum wells

Abstract
Ga0.47In0.53As/Al0.48In0.52As single quantum wells grown by molecular beam epitaxy have exhibited photoluminescence emission from 9668 Å to the 1.55-μm bulk emission at 4 K. The emission at 9668 Å is 0.474 eV above the band gap of GaInAs. The single quantum well (SQW) is 15 Å wide which is the narrowest SQW reported in any III-V compound. The effect of varying the buffer layer of the SQW on the photoluminescence intensity of a 65-Å single quantum well is studied.
