Many-body effects in the capacitance of multilayers composed of Mott insulators

ORAL

Abstract

Inhomogeneous dynamical mean-field theory is employed to investigate the non-linearity of the capacitance of multilayer nanostructures. The multilayer nanostructures are constructed with semi-infinite metallic leads coupled via a strongly correlated (Mott insulating) dielectric barrier. Results on the effects of varying barrier thickness temperature, potential difference, screening length, and chemical potential will be presented. In addition, we also intend to examine phase separation effects which have been experimentally measured to enhance the many-body capacitance over the geometric capacitance.
