Unchanged thermopower enhancement at the semiconductor-metal transition in correlated FeSb${}_{2-x}$Te${}_x$

P. Sun, M. Søndergaard, Y. Sun +3

Substitution of Sb in FeSb${}_2$ by less than 0.5% of Te induces a transition from a correlated semiconductor to an unconventional metal with large effective charge carrier mass $m^*…
