The optical properties of ZnO:Al films deposited on the (0001) surface of ε-GaSe single crystals
Abstract
ZnO:Al-GaSe:Cd heterojunctions were obtained by the thermal treatment of Cd-doped GaSe lamellae covered with a Zn nanometric layer containing different Al concentrations. The heterostructures were structurally (XRD) and optically (reflection spectra and dielectric permittivity for 1.5÷5.0 eV) analyzed.
