Research Abstract
The conduction behaviour of different compositions of the Bi1-xTex system with 30£ x£ 60 at. % is ohmic. Transition from metallic to semiconducting behaviour could be observed as the ambient temperature exceeds a certain value dependent on both x and the conditions of annealing. The activation energy of conduction (d Es ) calculated in the semiconducting region varied with x in an unsequential manner emphasizing the role of the existing different phases. However, the change in electrical conductivity could be attributed to a corresponding change in d Es
