Abstract

Here we investigate how charge transport properties scale down to the nanoscale regime, comparing the properties to standard semiconductor materials and providing a perspective on what it means to device manufacturing. Strontium titanate - the prototypical oxide material - has been widely studied for applications in thermoelectrics, nanoelectronics, catalysis, and other uses. We investigated how charge transport is effected at interfaces to strontium titanate under a wide range of conditions - by varying contact size, interface shape, dopant concentration, surface structures and in various combinations and relate the results to experiments utilizing standard semiconducting materials such as silicon and gallium arsenide. Also, the results of the analysis has wide ranging implications, especially for ferroelectric perovskite materials and serves as the basis for understanding and controlling switching effects - both polarization and oxygen migration based switching.
