Fundamental Properties:
Palladium diselenide (PdSe₂) is a layered transition metal dichalcogenide (TMD) characterized by its unique pentagonal crystal structure. It exhibits a transition from semimetallic behavior in bulk form to semiconducting properties in thinner layers. Monolayer PdSe₂ has an indirect bandgap of approximately 1.3 eV, which enables its use in optoelectronic and photonic applications.
PdSe₂ is highly stable under environmental conditions, shows strong anisotropic properties, and has excellent carrier mobility. These characteristics make PdSe₂ an attractive material for advanced applications in electronics, sensing, and energy storage. Additionally, its unique electronic structure and catalytic activity contribute to its suitability for hydrogen evolution reactions (HER) and other energy-related applications.
Applications:
Optoelectronics: The layer-dependent bandgap and anisotropic optical properties of PdSe₂ make it ideal for photodetectors and light sensors.
Electronics: High carrier mobility and tunable electronic properties enable its use in field-effect transistors (FETs) and other electronic devices.
Energy Applications: PdSe₂ demonstrates catalytic activity for HER and has potential as a material for batteries and supercapacitors.
Sensors: PdSe₂-based sensors exhibit high sensitivity and environmental stability, making them suitable for detecting gases and chemicals.
Quantum Technologies: Its unique electronic structure supports research in quantum computing and advanced material systems.
