Controlling resistance degradation of high-permittivty dielectrics by bulk and interface Fermi level engineering
Abstract
Ionic space charge layers and electrode oxygen permeability offer the opportunity to control andpotentially suppress resistance degradation of high permittivity dielectrics. The project will provide ascientific understanding of the influence of ionic space charge layers on the resistance degradation of highpermittivity dielectrics, which has not been investigated to date. Design principles for combinations of electrode materials and dopants, which can suppress resistance degradation and improve stability of highpermittivity dielectrics in harsh environments, are the major outcome of this proposal. Ionic space charge layers will be modified by controlling the bulk and interface Fermi energies using suitable electrode materials and bulk doping, respectively.
