Defect structure of undoped and Pb-doped Bi/sub 2/Se/sub 3/ single crystals

Abstract

We present the results of studies of some transport coefficients and optical properties in the IR region of both undoped and Pb-doped Bi/sub 2/Se/sub 3/ single crystals with the aim of explaining some anomalies in the dependence of the concentration of free current carriers on the content of incorporated Pb atoms.
