Abstract
We present magneto-photoluminescence of a ZnTe/ZnSe multilayer structure in which the clustering of Te atoms results in the formation of columns of type-II ZnSe:Te quantum dots. This unique geometry permits the observation of strong Aharonov–Bohm oscillations in both the emission energy and peak intensity with increasing magnetic field. Furthermore, far-infrared optically detected resonance techniques exhibit resonances that are ascribed to the activation and recapture of electrons by different subsets of quantum dots.
