Abstract
Temperature variation of electrical conductivity in two crystallographic di rections (sigma(parallel to) and sigma(perpendicular to)) of p-Bi2Te3 cryst als has been measured. The anisotropic factor, sigma(parallel to)/sigma(per pendicular to), shows an exponential form involving an activation energy. T his can be interpreted as an effect of defects between the layers on the el ectronic density of states.
