ZT=S2σTκcap Z cap T equals the fraction with numerator cap S squared sigma cap T and denominator kappa end-fraction Where each variable represents a vital physical property:

The keyword "" (or zT ) primarily refers to the dimensionless figure of merit , a critical metric used to evaluate the efficiency of thermoelectric materials . These materials are unique because they can convert waste heat directly into electricity (the Seebeck effect) or use electricity to provide cooling (the Peltier effect). Understanding the ZT Formula ZT=S2σTκcap Z cap T equals the fraction with

(Electrical Conductivity): The material's ability to allow the flow of electric current. ZT=S2σTκcap Z cap T equals the fraction with

The efficiency of a thermoelectric material is defined by the following equation: ZT=S2σTκcap Z cap T equals the fraction with
