Abstract : This paper reports some new data on the transport properties of SmS and Sm0.8Tb0.2S at high pressures. Using thermo-power as a tool, we have established that the semiconductor-metal phase boundary in SmS terminates at a critical point. Further the high pressure behaviour of Sm0.8Tb0.2S suggests that at pressures greater than 12 kbar, the Samarium ion is in the fully trivalent state.
