Highly Dispersive Electron Relaxation and Colossal Thermoelectricity in the Correlated Semiconductor FeSb${}_2$

Peijie Sun, Wenhu Xu, Jan M. Tomczak +4

We show that the colossal thermoelectric power, $S(T)$, observed in the correlated semiconductor FeSb${}_2$ below 30\,K is accompanied by a huge Nernst coefficient $\nu (T)$ and magneto…
