The Seebeck coefficients were found to be positive for all the samples in the temperature range between 300K and 550K. Although no effective enhancement of the Seebeck coefficient was observed, doping with Cr by means of either substitution or intercalation clearly not only improved the electrical conductivity but also lowered the thermal conductivity of Bi2Te3. As a result of the improvement, the figure of merit ZT is increased up to 0.8 and 0.65 at 300K for 1% intercalated and 1% substituted Bi2Te3, respectively.
