摘要：
We have determined the pressure dependence of the direct bandgap, ionicity, transverse effective charge and refractive index for CdTe. The study is performed using the sp(3)s* semi-empirical tight-binding method with the scaling law and Murnaghan's equation of state. All these properties were found to have a sublinearity behaviour with the pressure. The results are compared with other works. (C) 2002 Elsevier Science Ltd. All rights reserved.
