Properties of ZnSe(Cd) single-crystal layers
- Fed`kovich State Univ., Chernovtsy (Ukraine)
The physical properties of all of the most important semiconductors can be modified by isovalent doping . In particular, ZnSe(Te) crystals exhibit strong {gamma}-induced luminescence (20% at 300 K), whose intensity remains virtually unchanged up to a dose of 10{sup 6} Gy. Since the radiative recombination in this material gives rise to predominantly red emission, its application in optoelectronics is limited because the main problem is the development of blue-green light-emitting diodes. The replacement of Te by another isovalent dopant can be expected to modify the emission spectrum, without affecting other useful properties. Previously, we observed a marked increase in the intensity of the blue-green photoluminescence (PL) band in Cd-doped ZnSe crystals. In this work, we studied the absorption and emission properties of ZnSe(Cd) layers.
