ZnTe quantum wells

Abstract

This chapter discusses nanostructures with ZnTe quantum wells and MnTe, (Zn,Mn)Te or (Zn,Mg)Te barriers. Photoluminescence (PL) from ultrathin ZnTe/Zn0.30Mg0.70Te quantum wells (QW) is reported in literature. The quantization in ZnTe/(Zn,Mg)Te QWs is evidenced by a blueshift of PL spectra. Excitonic transitions in ZnTe/(Zn,Mn)Te QWs and their dependence on well width are studied in literature. Center-of-mass localized (COM) localization of both, heavy- and light-hole exciton polaritons, is found in wide ZnTe/(Zn,Mg)Te QWs. Longitudinal optical (LO)-phonon assisted relaxation of hot excitons was demonstrated in ZnTe/MnTe single quantum well (SQW) samples, where thin MnTe barriers allowed the excitons to tunnel out of the well.
