摘要
The invention relates to solid state physics, in particular to the methods for investigation of parameters of the optical-absorption edge. A method for determination of temperature dependence of the width of optical pseudogap of solids includes investigation of solids. According to the invention, one carries out temperature iso-absorption investigations of the optical-absorption edge of solids at two values of absorption coefficientand, for which one obtains two temperature dependences of the width of quasi-forbidden zoneand, after that one obtains temperature dependence of the width of optical pseudogap. The method proposed makes it possible to determine quickly, reliably and effectively the width of optical quasi-gap of solids by results of iso-absorption investigations of the absorption edge, avoiding tedious spectral investigations.
