Cu2SnS3 熱電素子への電極形成とその低接触抵抗化

抄録

We have fabricated Cu2SnS3(CTS) thermoelectric (TE) legs with electrodes. Consequently, Al is found to be the most suitable electrode material for the CTS TE legs fabricated by the monobloc sintering among Al, Mo, W, Cu, Sn, Zn and Ag. An intermediate layer consisted of CuS and/or Al/CTS is found to be effective to reduce the contact resistance (CR). The CR of less than 10-1 cm2 can be obtained.
