Carrier Doping and Dynamics in Correlated Oxides
Abstract
The overarching goals of the project include fundamental studies of carrier doping mechanisms of correlated oxides and in-situ measurements at a synchrotron beamline. Recently, we have designed a new approach to dope correlated oxides using biological interfaces. This methods allows electron doping that is confined to near-surface regions with no need for external energy input. This is accomplished by enzymatic anchoring to electrodes placed on the correlated oxide surface. This mechanism has been studied in detail using angle dependent NEXAFS to show that the doping is confined to the top few nms. Collaborative studies on the doping using different enzymes have allowed us to establish the general principles for near-surfacedoping of correlated nickelates.
