Paper Abstract
CdTe ultra-thin quantum wells (UTQWs) within ZnTe barriers were grown by pulsed beam epitaxy (PBE) on GaAs(001) substrates. In-situ reflection high energy electron diffraction (RHEED) patterns and real-time spot intensity measurements indicated a high structural quality of the QWs. Low temperature photoluminescence (PL) experiments indicated a clear influence of the growth temperature on the structural properties of the samples. The 2 monolayer (ML) thick UTQW grown at Ts = 270°C exhibited an intense and sharp peak at 2.26 eV whereas the 4 ML thick UTQW (Ts = 290°C) presented an intense peak at 2.13 eV and a weak one around 2.04 eV. This behavior is discussed in terms of Cd re-evaporation at the higher Ts.
