In article number 2003168, Yu Pan, Chenguang Fu, Claudia Felser, and co‐workers investigate the thermoelectric properties of a novel nodal line semimetal, YbMnSb 2 . 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 YbMnSb 2 is found to be competitive with conventional high‐performance thermoelectric semiconductors, even binary Bi 2 Te 3 single crystals.
