摘要： Provided is a thermoelectric device including two legs having a rough side surface and a smooth side surface facing each other. Phonons may be scattered by the rough side surface, thereby decreasing thermal conductivity of the device. Flowing paths for electrons and phonons may become different form each other, because of a magnetic field induced by an electric current passing through the legs. The smooth side surface may be used for the flowing path of electrons. As a result, in the thermoelectric device, thermal conductivity can be reduced and electric conductivity can be maintained.
