Nernst Effect in Semimetals: The Effective Mass and the Figure of Merit
... Conceptually, it is easier to picture this phenomenon [24] in an Ettingshausen geometry: when electrons loose their impulsion in a collision with phonons, the electric current gives rise to an entropy current of phononic origin, hence a finite Ettingshausen effect. Since the Bridgman relation ties t ...
