Definition
A high-k dielectric is an insulating material with a dielectric constant higher than silicon dioxide, allowing greater gate capacitance at a physically thicker dielectric layer.
Application
High-k gate dielectrics such as hafnium-based materials reduce gate leakage while maintaining electrostatic control in scaled MOS transistors.
