Field-effect transistors with high-sensitivity gates

摘要

A field-effect transistor (FET) includes a source electrode, a drain electrode, a gate electrode, a gate dielectric, and a semiconductor layer that functions as an active channel of the transistor. The active channel is configured to carry a current between the source and drain electrodes and has a conductivity responsive to voltages applied the gate electrode. The gate dielectric is located between the gate electrode and the semiconductor layer and includes a quasi-1D charge or spin density wave material.
