Device Description & Features:
High-Mobility 2D Semiconductor: Black phosphorus (BP) is a layered van der Waals material with a layer-dependent direct bandgap (~0.3 eV in bulk to ~1.5 eV in monolayer) and high carrier mobility. Back-Gated FET Configuration: The SiO₂/Si back-gate structure supports electrostatic control, with low-power operation and high on/off current ratio.
Mechanically Exfoliated Few-Layer BP: For charge-transport studies.
Gold Electrodes: Forms low-resistance Ohmic contacts, supporting carrier injection efficiency.
Anisotropic Transport: BP exhibits direction-dependent electrical properties, enabling directional electronic applications.

Applications:
Field-Effect Transistors (FETs):
BP FETs exhibit high mobility, gate tunability, and tunable bandgap, and they are used for nanoelectronic applications. Flexible & Low-Power Electronics:
BP’s mechanical flexibility can support use in wearable devices, transparent electronics, and flexible transistors. Infrared Optoelectronics & Photodetectors:
The layer-dependent bandgap allows BP to function as an infrared-sensitive material for photodetectors and near-infrared optoelectronics. Neuromorphic & Quantum Computing:
The anisotropic electronic properties of BP can support use in neuromorphic and quantum computing applications.
