Large Thermoelectric power factor in CrN

ORAL

Abstract

We report the electrical resistivitiy and thermoelectric power of stoichiometric and hole-doped chromium nitride (CrN). The results indicate a considerably large power factor, of the order of 1(microW/cmK2) at 400 K, increasing with temperature. Hall effect measurements were used to elucidate the mechanism of electronic transport in this system, in order to optimize its properties. The easy of grow in the form of nanoparticles and thin films, along with a good thermal stability up to 700 K, could make this material interesting for applications at moderate temperatures.
