Impact of Chemical States on the Effective Work Function of Metal Gate and High-kappa Dielectric Materials on Novel Heterostructures

An experimental and theoretical approach is taken to determine the effect of a heterojunction on the effective work function in a metal/high-? gate stack, the characteristics of aqueous hydrochloric acid cleaned (aq-HCl) GaN surface and the interface between GaN and Al2O3, HfO2 and GaON. The invest...
