Thermoelectric Materials
In article number 2005931, Sung Wng Kim, Hyun‐Sik Kim, Kyu Hyoung Lee, and co‐workers discuss the weighted mobility ratio as an important parameter that determines the conversion efficiency of thermoelectric materials. Material design to increase the weighted mobility of majority carriers simultaneously improves the electronic and thermal transport properties of narrow‐bandgap...
Thermoelectrics, which can generate electricity from a temperature difference, or vice versa, is a key technology for solid‐state cooling and energy harvesting; however, its applications are constrained owing to low efficiency. Since the conversion efficiency of thermoelectric devices is directly obtained via a figure of merit of materials, zT, which is related to the electronic and thermal transport...
