 The study investigates the Seebeck effect in structured nanowires using the green's function method and Landau-Butterker formula to determine the TE transport properties, finding a large coefficient when transmission gaps occur due to quantum interference, which can be controlled by the geometry of the nw's. This information is useful for designing nanoscale TE devices with the same material doping rather than n, type and p, type materials.
