IPC: H01L35/26
Filed: 1990-05-19
Abstract: PURPOSE:To eliminate the high electric resistance of a thermoelectric conversion element caused by rectification so as to lessen the element in power loss by a method wherein a doped layer higher than the other part in impurity concentration is provided near the electrode joint of the thermoelectric conversion element. CONSTITUTION:In thermoelectric conversion elements 1 and 2 which generate an electromotive force through a temperature gradient, a doped layer 3 higher than the other part in impurity concentration is provided near to a joint 11 between an electrode 21 through which an electric power is led out and the element 2. That is, when a certain voltage is applied to the joint 11, a current flowing through the joint 11 is proportional to carrier density, so that the joint 11 becomes small in electrical resistance when carriers are enhanced in concentration. Therefore, a doped layer is formed to enhance carriers in density, whereby the high resistance of an electrode joint caused by rectification can be eliminated. By this setup, a thermoelectric conversion element can be lessened in power loss.
