摘要：

Strongly compensated samples of CdSe with 1017−1018 cm−3 have been investigated. Two samples exhibit metallic and three non-metallic behaviour. The various regions of impurity-band conductivity have been identified from Hall and resistivity measurements. The density of states at the Fermi level has been estimated and compared with theory. A negative magnetoresistance has been observed in both metallic and non-metallic samples. A strongly temperature- dependent positive magnetoresistance in the variable-range-hopping regime is explained in terms of a simple extension of the Mikoshiba theory. © 1979 Taylor & Francis Ltd.
