Re-Doped WSe₂ Crystals

Re-Doped WSe₂ Crystals

Re-doped WSe₂ is a layered transition metal dichalcogenide (TMDC) with a van der Waals structure, combining the intrinsic properties of WSe₂ with modified electronic and catalytic properties introduced by rhenium doping. Rhenium doping introduces additional charge carriers, modifies the band structure and the material’s electronic, optical, and catalytic properties, supporting research and applications in optoelectronics, spintronics, and energy conversion technologies.
