General description
Thermoelectric properties of bismuth antimony telluride (BiSbTe) has been studied in detail.1 A study reports the preparation of p-type BiSbTe by melting solidification method in static magnetic field. Concentration of holes in p-type BiSbTe can be regulated by tellurium evaporation annealing technique. Thermoelectrical properties of dense p-type BiSbTe was compared to nanosized antimony-doped p-type BiSbTe. The properties were found to be enhanced.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.
