Abstract

The relationships between Mg composition, band gap, and lattice characteristics are investigated for Cd_1−xMg_xTe barrier layers using a combination of cathodoluminescence, energy dispersive x-ray spectroscopy, variable angle spectral ellipsometry, and atom probe tomography. The use of a simplified, yet accurate, variable angle spectral ellipsometry analysis is shown to be appropriate for fast determination of composition in thin Cd_1−xMg_xTe layers. The validity of using high-resolution x-ray diffraction for CdTe/Cd_1−xMg_xTe double heterostructures is discussed. The stability of CdTe/Cd_1−xMg_xTe heterostructures are investigated with respect to thermal processing.
