Abstract

Using ballistic NEGF, the fortran code calculates the Seebeck coefficient and electrical conductivity from IV characteristics on a three-layer superlattice (film) structure. A temperature difference is imposed on the device, which produces a current (Seebeck effect). A bias is applied such that the net current in the device is zero. This applied bias is the Seebeck voltage. The slope of the IV curve at the Seebeck voltage is the electrical conductivity.
