Thermoelectric Properties of Bi-Sb-Te-X Compounds Prepared by MA-PDS Method
Published online by Cambridge University Press: 21 March 2011
Abstract
A great potential for further improving the room-temperature figure of merit (Z) has been identified by dispersing a small fraction of Ag in the (Bi0.25Sb0.75)2Te3 alloy. The maximum Z of 3.41×10−3K−1, 17% higher than that of the unadded, is attained at 0.02wt% Ag. Addition of BN, either alone or in combination with Ag, however, does not generate a favorable figure of merit.
