Abstract
An unusually high homogeneity of electrical properties was found in Sn-dope d Bi2Te3 single crystals. The Seebeck coefficient, which is sensitive to fl uctuations in charge carrier concentration, remains unchanged even when the amount of introduced Sn impurity is increased. This fact is explained in t erms of the model of resonance impurity states. (C) 2000 MAIK "Nauka/Interp eriodica".
