Device Description & Features:
Anisotropic 2D Semiconductor: Rhenium disulfide (ReS₂) is a layered transition metal dichalcogenide (TMD) with a low-symmetry triclinic crystal structure, leading to strong in-plane anisotropic transport properties. Layer-Dependent Bandgap: Few-layer ReS₂ has a tunable direct bandgap (~1.35 eV in monolayer form), making it suitable for high-performance optoelectronic applications. Back-Gated FET Configuration: The SiO₂/Si back-gate structure ensures efficient electrostatic control, allowing for low-power operation and a high on/off ratio.
Mechanically Exfoliated Layers: Produces high-quality, intrinsic ReS₂ films with minimal defects and superior carrier mobility.
Gold Electrodes: Forms low-resistance Ohmic contacts, enhancing charge injection efficiency.

Applications:
High-Performance Field-Effect Transistors (FETs):
Exhibits anisotropic electronic transport, enabling directionally tunable nanoelectronics. Flexible & Low-Power Electronics:
Ideal for wearable and flexible transistors, benefiting from ReS₂’s mechanical flexibility. Optoelectronic & Photonic Devices:
