WSSe Crystals

WSSe Crystals

WSSe is a layered transition metal dichalcogenide (TMDC) alloy with a van der Waals structure and tunable bandgap and optoelectronic properties. As a mixed chalcogenide, WSSe combines the characteristics of WS₂ and WSe₂, supporting its use in quantum research, optoelectronics, and energy-related applications.
