We report on the correlated nonvolatile resistance and capacitance switching in Pt/LaAlO3/Nb:SrTiO3 heterostructures. The pristine devices show the typical characteristics of a Schottky junction; however, after forming, a reverse bias switches the device into a low resistance and high capacitance st...
