Abstract Scope |
Despite the efforts devoted to the development of new thermoelectric materials, it is a fair and unfortunately not so surprising that bismuth telluride based materials are still the only one used in commercial thermoelectric devices. The performances of these materials are well known and their synthesis rather straight forward, however the relationships between their properties and the way they are produced are still puzzling as it is mainly the type and number of defects that govern their electronic transport properties. In this presentation, we will show our preliminary results on our attempts to tame the defect chemistry in these materials, both in terms of pure thermoelectric performance “ZTmax” and temperature at which this occurs (Tmax). |
