Screening of transition (Y, Zr, Hf, V, Nb, Mo, and Ru) and rare-earth (La and Pr) elements as potential effective dopants for thermoelectric GeTe – an experimental and theoretical appraisal

A report on an improvement in the thermoelectric performance of GeTe via intentional creation of more electrically dormant Ge vacancies (in contrast to classical approaches) and modulating/balancing it with optimized Zr-doping.
