Abstract :
p-Type Bi2Te3-based thermoelectric materials with a nominal composition of CrxBi2Te3 (0 ≤ x ≤ 0.1) have been prepared and characterized by X-ray diffraction. The solubility limit of Cr in Bi2Te3 for equilibrium growth of bulk crystals was found to be around 4 at.%. Detailed charge transport datas including electrical conductivity, Seebeck coefficient are presented in order to investigate the effect of Cr on the thermoelectric properties of Bi2Te3.
