Graphene FET Device

Device Structure:
Conductive Si Substrate / 300 nm SiO₂ Layer / Graphene Channel / Cr+Au Electrodes

Device Description & Features:
High-Performance 2D Material: Graphene is a single-layer honeycomb lattice of carbon atoms, offering ultrahigh carrier mobility, linear band dispersion, and tunable electronic properties. Back-Gated FET Configuration: The SiO₂/Si back-gate structure provides effective electrostatic control, enabling high carrier mobility and low-power operation.
Metal Contact Engineering: The Cr+Au electrodes ensure low-resistance contacts, optimizing carrier injection and transport. Solution-Processed or CVD-Grown Graphene:
CVD-Grown Monolayer Graphene: Ensures large-area uniformity for scalable device fabrication.
Mechanically Exfoliated Graphene: Preserves intrinsic electronic properties with minimal defects, optimizing carrier transport.
