Metastable Conduction States In Mo2S3: Pulse Conductivity And Thermoelectric Power, Roger D. Kirby, R.L. Fagerquist

Roger Kirby Publications

Mo₂S₃ is a linear-chain-structure compound which has two inequivalent zig-zag Mo chains parallel to the b axis. It undergoes at least two phase transitions below room temperature (at 182 and 145 K upon cooling). X-ray-diffraction measurements show that both incommensurate and commensurate structural distortions are associated with the phase transitions. We repot here the results of electrical-conductivity and thermoelectric-power measurements on Mo₂S₃ . By using pulsed electric currents to rapidly heat and cool the sample while electrical-resistivity or thermoelectric-power measurement are being made, we are able to show that below the lower-temperature phase transition, …
