摘要：

Optical-absorption studies of the band gap Eg in a 150-m-thick natural single crystal of FeS2 for temperatures T up to 425 K are presented. Different contributions to the temperature dependence of Eg are discussed. It is argued that the variation of the form Eg(T)=Eg(0)+aT+bT2, with the parameters Eg(0)=0.835 eV, a=4.0×10-5 eV/K, b=-7.4×10-7 eV/K2 obtained from the best fit, provides a good physical interpretation of the data. © 1979 The American Physical Society.
