Bismuth Telluride Cube

Description
Bismuth Telluride is a narrow gap layered semiconductor with a trigonal unit cell. It is a semiconductor which alloyed with antimony or selenium is an efficient thermoelectric material for refrigeration or power generation. Bismuth Telluride is a considered a classic thermoelectric material with a Seebeck coefficient of −287 μV/K at 54 °C, and its derivatives are in wide use both in industry and in research. Here at C-Therm we measured its thermal conductivity with a C-Therm TCi sensor across three tests of five data samples each. Each test had a relative standard deviation of <0.8% and overall there was a deviation of <1.5% across three tests. The mean of these tests agreed with the literature accepted value of Bi2Te3 thermal conductivity within <1%.
