Doping-induced topological transition and enhancement of thermopower in the Dirac-semimetal system Cd${}_{3-x}$Zn${}_x$As${}_2$

J. Fujioka, M. Kriener, D. Hashizume +3

Cd${}_3$As${}_2$ is one of the prototypical topological Dirac semimetals. Here, we manipulate the band inversion responsible for the emergence of Dirac nodes by alloying Cd${}_3$As${}_2$ w…
