Abstract
A dependence of energy gap on composition x for Cd1-xZnxTe (x = 0-0.06) was found combining x-ray diffraction and low temperature photoluminescence measurements (free exciton energy) on Cd1-xZnxTe single crystals. The use of this dependence for evaluation of Zn content (x) in the crystals shows very good agreement with the near infrared absorption method. Published dependences Eg(x) are reviewed and compared with the dependence Eg(x,T = 4 K) = 1.606 + 0.520x + 0.254x2 derived in this work.Keywords
