Abstract
A critical examination is presented of the available experimental evidence relating to the frequency dependence of the electrical conductivity of a wide range of disordered and amorphous semiconductors and insulators. It is pointed out that there is no justification for regarding these effects as true bulk phenomena, and there are good reasons to expect that contacts and interfaces play a dominant role.Keywords
