Photocurrent spectra in an In 0.53 Ga 0.47 As/In 0.52 Al 0.48 As multi-quantum wells structure containing 9.4 nm wide wells were measured at room temperature in electric fields. The exciton peaks of ground-state transitions shifted fairly in 167 kV cm -1 as the quantum confined Stark effect. Stark s

We observed that a series of peaks, which were clearly extracted from a photocurrent difference spectrum, corresponded to interband optical transitions of an In 0.53 Ga 0.47 As/ In 0.52 Al 0.48 As multi-quantum wells structure. The nonparabolic tendency of the electron effective mass was suggested f
InGaAs/InP multi-quantum well structures, grown by metal-organic vapour phase-epitaxy, were investigated by Raman spectroscopy and X-ray diffractometry to analyse the influence of precursor gas switching parameters on the interface abruptness. Owing to carry-over effects, InAsP is formed at the InGa
