Abstract
The effect of electron and X-ray irradiation on the optical characteristics of CdZnTe/ZnTe quantum-size structures has been investigated. A comparison between the results of both irradiations has shown an essential role of el ectron excitation in radiation enhancement of Cd diffusion that is one of t he reasons for degradation of the II-VI-based quantum-size structures. High defect density in the barrier layer and high stress level are considered t o serve as additional reasons for degradation of the CdTe-based quantum siz e structures under irradiation.
