Device Structure:
SiO₂/Si Substrate / WSe₂ Channel / Au or Cr+Au Electrodes
Device Description & Features:
High-Performance 2D Semiconductor: Tungsten diselenide (WSe₂) is a layered transition metal dichalcogenide (TMD) with a layer-dependent bandgap (monolayer: direct bandgap ~1.6 eV, multilayer: indirect bandgap), making it highly suitable for electronics and optoelectronics.
Back-Gated FET Configuration: The SiO₂/Si substrate serves as a global back-gate, providing efficient electrostatic control over the WSe₂ channel.
Stable p-Type or Ambipolar Conductivity: WSe₂ can function as a p-type or ambipolar transistor, depending on doping, contact engineering, and gate voltage tuning.
Mechanically Exfoliated or CVD-Grown WSe₂: Ensures high crystal quality, minimal defects, and superior electronic performance.
Ohmic Contact Engineering: Au or Cr+Au electrodes provide low-resistance metal contacts, optimizing charge injection.
