Abstract

3-Zn;Sb3 Is A Promising High Temperature Thermoelectric Materials With A High Power Factor Sea Where S Is The Thermopower And A Is Electrical Conductivity . It Is Found That The Properties Of (3-Zn4Sb3 Can Be Altered By Addition Of Sn. In This Paper The Electronic And Thermal Properties Of 13-Zn4Sb3 Are Given In Detail . Electrical Resistivity And Absolute Thermqpower Are Measured As A Function Of Temperature From Room Temperature To 300°C .Both Electrical Resistivity And Thermopower I Values Are Found To Increase With Addition Of Tin. It Is Observed Experimentally That At Lower Tin Concentrations (<I Weight %) Power Factor Remains Close To That Of 3-Zn4Sb3 And At Higher Concentration Of Sn Power Factor Decreases . Thermal Conductivity K, Of These Sn Added Zn.,+Sb3 Was Found To Be Lower Than That Of (3-Zn4Sb3 Showing A Noticeable Enhancement In ZT (=S 2at/K)At Low Concentration Of Tin.
