Autor: K. El-Hami, R. Abdia, A. Oubraham, A. Abouharim

Publikováno v: Lecture Notes in Electrical Engineering ISBN: 9783030364748

In this paper, we present investigations of electron hopping conduction by measuring the temperature dependence of electrical resistivity of n- CdAs2 semiconductor. The resistivity was measured without magnetic field as well as in its presence. The e
