Pressure-induced Metallization of Carbon Disulfide

ORAL

Abstract

We will report high pressure electrical resistivity measurements on solid CS$_{2}$ in diamond anvil cell to 60GPa. The result shows a steady decrease in resistivity to that of metal at around 55GPa. Its visual appearance of CS$_{2}$ also supports its insulator-metal transition: the initially transparent CS$_{2}$ becomes opaque and eventually reflective with increasing pressure. We will also present a plausible mechanism for the observed metallization.
