  • Abstract
    In this study comprehensive experimental measurements together with a physical picture demonstrate that, regardless of poly-Si doping, the defects creation in the dielectric close to the poly-Si/HfO2 interface is responsible for the observed effective WF change. These defects are amphoteric and spatially nonuniformly distributed.
