Thermoelectric Materials: Thermoelectric Properties of Novel Semimetals: A Case Study of YbMnSb 2 (Adv. Mater. 7/2021)

Abstract

In article number 2003168, Yu Pan, Chenguang Fu, Claudia Felser, and co-workers investigate the thermoelectric properties of a novel nodal line semimetal, YbMnSb2. The Dirac bands guarantee high charge-carrier mobility, and, simultaneously, a regular band provides a large density of states leading to a large thermopower. The power factor of single-crystal YbMnSb2 is found to be competitive with conventional high-performance thermoelectric semiconductors, even binary Bi2Te3 single crystals.
