摘要:
A thermoelectric device is provided. The thermoelectric device includes first and second electrodes, a first leg, a second leg, and a common electrode. The first leg is disposed on the first electrode and includes one or more first semiconductor pattern and one or more first barrier patterns. The second leg is disposed on the second electrode and includes one or more second semiconductor pattern and one or more second barrier patterns. The common electrode is disposed on the first leg and the second leg. Herein, the first barrier pattern has a lower thermal conductivity than the first semiconductor pattern, and the second barrier pattern has a lower thermal conductivity than the second semiconductor pattern. The first/second barrier pattern has a higher electric conductivity than the first/second semiconductor pattern. The first/second barrier pattern forms an ohmic contact with the first/second semiconductor pattern.

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.
