Fundamental Properties:
Rhenium diselenide (ReSe₂) is a layered transition metal dichalcogenide (TMD) with a distorted 1T crystal structure, similar to its sulfide counterpart, ReS₂. This structure results in weak interlayer coupling and strong in-plane anisotropy, giving ReSe₂ nearly layer-independent properties. Its indirect bandgap of approximately 1.2 eV (monolayer) and high environmental stability make it a promising material for advanced electronic and optoelectronic applications.
ReSe₂ also exhibits strong anisotropic optical and electronic behavior, making it suitable for applications requiring polarization sensitivity. Its mechanical flexibility and chemical stability further enhance its utility in next-generation devices.
Applications:
Optoelectronics: ReSe₂ is ideal for photodetectors and light sensors due to its layer-independent bandgap and anisotropic optical properties.
Electronics: Its high mobility and anisotropic electronic properties make ReSe₂ a promising material for field-effect transistors (FETs).
Sensors: ReSe₂-based sensors offer excellent sensitivity and stability for gas and chemical detection.
Energy Applications: ReSe₂ has potential as a catalyst for hydrogen evolution reactions (HER) and as an electrode material in energy storage devices.
Photonics and Nonlinear Optics: ReSe₂’s anisotropic optical response enables its use in polarization-sensitive photonic devices.
