The Thermoelectric Performance Enhancement of N-type BiTeSe Alloys by Addition of ZnAlO

摘要：

　　A series of n-type BiTeSe/ZnAlO composites were prepared by zone melting method.Thermoelectric properties,including the electrical conductivity,Seebeck coefficient and thermal conductivity,were measured in the temperature range of 300-550K.Results show that electrical conductivities have been slightly lowered because ZnAlO has reduced the carrier concentration.However,the prematurely happened intrinsic excitation has shifted α peak to low temperature,which consequently shifted peak ZT to lower temperatures.Thus,BiTeSe/ZnAlO with significantly enhanced ZT value at 300 K is more attractive for cooling applications at ambient temperature.
