This chapter discusses a variety of device concepts that are based on the conductive interface between LaAlO3 and SrTiO3. The interface between these two insulating oxides spontaneously forms a high mobility, two dimensional electron gas when the LaAlO3 thickness exceeds a critical value. At the critical thickness, the insulator-metal transition can be reversibly controlled using externally applied fields, and furthermore can be defined on the extreme nanoscale using a conducting AFM probe. After an initial discussion of macroscopic field effects at this interface, the chapter describes the use of conducting AFM lithography to fabricate nanoscale devices. Nanoscale wires, diodes, transistors, and photodetectors can be created, modified, and erased. Possible future integration with silicon-based electronics is discussed, along with possible applications in the fields of spintronics, quantum information processing, and quantum simulation.
