Giant enhancement of cryogenic thermopower by polar structural instability in the pressurized semimetal MoTe2

Hidefumi Takahashi, Kento Hasegawa, Tomoki Akiba +3

We found that a high mobility semimetal 1T'-MoTe2 shows a significant pressure-dependent change in the cryogenic thermopower in the vicinity of the critical pressure, where the pol…
