WebNucleation and Crystallisation of Hafnium Compounds and Thin Films. Hafnia and hafnium silicate are leading high-k materials to replace SiO2 in CMOS devices. In this thesis the re WebJ E exp q − t + qE/ i k BT 1 where t is the energy level of a trap with respect to the conduction band of the gate oxide, E is the effective electric field across the insulator, and i is the high-frequency dielectric constant. Thus, the ln J leakage/E vs E1/2 graph should have a linear relationship with the P-F regime. The leakage-current ...
