  • Abstract
    We report on a multiscale simulation approach that includes both macroscopic drift-diffusion current model and atomistic quantum tunneling model. The models are solved together in a self-consistent way inside a single simulation package. We compare the high-K gates based on HfO2 and ZrO2 with a SiO2 gate of the same equivalent thickness and show the effect of the tunneling current on transistor performance.
