Device Description & Features:
High-Performance 2D Semiconductor: Molybdenum disulfide (MoS₂) is a layered transition metal dichalcogenide (TMD) with a layer-dependent bandgap (monolayer: direct, multilayer: indirect), making it ideal for high-performance electronics and optoelectronics. Back-Gated FET Configuration: The SiO₂/Si back-gate structure provides efficient electrostatic control, ensuring low-power operation and high on/off current ratio. Triangular MoS₂ vs. Exfoliated MoS₂:
CVD-Grown Triangular MoS₂: Ensures large-area uniformity for scalable device fabrication.
Mechanically Exfoliated MoS₂: Preserves intrinsic properties with minimal defects, optimizing carrier transport.
Metal Contact Engineering: Au+Cr+Au electrode structure ensures low-resistance Ohmic contacts, enhancing charge injection and carrier mobility.

Applications:
High-Performance Field-Effect Transistors (FETs):
MoS₂ FETs offer high mobility, strong gate control, and ultrathin channels, suitable for next-generation nanoelectronics. Flexible and Low-Power Electronics:
Ideal for wearable devices, transparent electronics, and flexible transistors. Optoelectronic & Photodetector Devices:
MoS₂ exhibits layer-dependent photoluminescence, making it useful in photodetectors, LEDs, and photovoltaics. Neuromorphic & Quantum Computing:
MoS₂’s tunable electronic and excitonic properties make it a potential candidate for neuromorphic computing and quantum electronics.
