The electrical resistance of $Mo_{0.5}W_{0.5}S_2$ single crystal under pressure

Özet

Single crystals of $Mo_{0.5}W_{0.5}S_2$ were grown by chemical vapour transport and direct vapour transport techniques. The crystals have been characterized by X-ray energy dispersive analysis and X-ray powder diffraction. The dc electrical resistance of the grown single crystals of $Mo_{0.5}W_{0.5}S_2$ was measured in Bridgman anvil setup to 8 GPa to identify occurrence of structural phase transitions. The drastic changes in electrical resistance were observed at~ 2.5 GPa and ~4.6 GPa, and are similar to the structural phase transitions in WS2 single crystals.
