Device Description & Features:
Heterostructure 2D FET: The combination of PdSe₂ and ReS₂ forms a unique type-II van der Waals heterojunction, permits high-efficiency charge transfer and enhanced carrier transport. Layer-Dependent Bandgap Engineering:
ReS₂: Anisotropic direct bandgap (~1.35 eV in monolayer), variable with layer thickness.
PdSe₂: Layer-dependent bandgap (from ~1.3 eV in few layers to metallic in bulk form), allowing enhanced electronic versatility. Back-Gated Configuration: The SiO₂/Si back-gate structure has functional electrostatic control, with low-power operation and high field-effect mobility. Mechanically Exfoliated 2D Layers: High-purity ReS₂ and PdSe₂ flakes retain intrinsic properties with minimal structural defects.
Gold Electrodes: Forms low-resistance Ohmic contacts, configured charge injection and carrier transport.
