cze	Fermi Surface and Thermoelectric Power of (Bi(1-x)Sb(x))(2)Te(3)/Ag,Sn/ Mixed Crystals	The Fermi surface anisotropy of (Bi1 ?xSbx)2Te3single crystals (0.25≤x≤1) was studied by analyzing the angular dependence of the frequency of Shubnikov?de Haas oscillations and the effect of tin and silver doping on the thermoelectric power in these crystals in the temperature range 77≤T≤300 K. It was shown that silver doping of (Bi1 ?xSbx)2Te3 mixed crystals produces acceptors, while silver in Bi2Te3acts as a donor. Tin also exhibits acceptor properties. Both tin and silver doping of p-(Bi1 ?xSbx)2Te3 mixed crystals decrease the thermoelectric power due to an increase in the hole concentration.
