Diodes with Breakdown Voltages Enhanced by the Metal-Insulator Transition of LaAlO${}_3$-SrTiO${}_3$ Interfaces

Abstract

Using the metal-insulator transition that takes place as a function of carrier density at the LaAlO${}_3$-SrTiO${}_3$ interface, oxide diodes have been fabricated with room-temperature breakdown voltages of up to 200 V. With applied voltage, the capacitance of the diodes changes by a factor of 150. The diodes are robust and operate at temperatures up to 270 C.
