Enhancement of the thermoelectric figure of merit in the Dirac semimetal Cd₃As₂ by band-structure and -filling control.

ABSTRACT: Topological materials attract a considerable research interest because of their characteristic band structure giving rise to various new phenomena in quantum physics. Besides this, they are tempting from a functional materials point of view: Topological materials bear potential for an enhanced thermoelectric efficiency because they possess the required ingredients, such as intermediate carrier concentrations, large mobilities, heavy elements etc. Against this background, this work reports an enhanced thermoelectric performance of the topological Dirac semimetal Cd₃As₂ upon alloying the trivial semiconductor Zn₃As₂. This allows to gain fine-tuned control over both the band filling and the band topology in Cd_3-x Zn _x</
