Abstract

A simple, externally heated opposed (Bridgman) anvil system has been developed for electrical resistivity measurements up to 8 GPa pressure and 400 degrees C. The whole system is automated, in which the application and measurement of pressure and heating of the sample are undertaken using an IBM PC and associated electronic and mechanical hardware. The system developed has a pressure control of about +/-1% and temperature control better than +/-2%. The setup has been calibrated using the high pressure-high temperature transitions in the electrical resistivity of Bi and Yb. The usefulness of the system developed has been demonstrated, by studying the resistivity behavior of glassy chalcogenide semiconductors at high pressure and high temperature.
