WebSep 1, 2024 · The higher dielectric constant results in higher gate capacitance which in turn increases the inversion charge. The increase of inversion charge results in higher drain current. Fig. 2 also shows that the on-state drain current ( Ion) is higher in CNT FET as compared with the other FETs.
The term high-κ dielectric refers to a material with a high dielectric constant (κ, kappa), as compared to silicon dioxide. High-κ dielectrics are used in semiconductor manufacturing processes where they are usually used to replace a silicon dioxide gate dielectric or another dielectric layer of a device.
