Novel ballistic electron emission microscopy experiments are reported, aimed to directly visualize and quantify the local inhomogeneities of the effective Schottky barrier height on Au/Nb:SrTiO3 Schottky junctions dominated by interfacial resistance switching effects. The voltage-dependent variation of the local barrier height of the nanometric patches could explain the non-ideal behaviour of the resistance switching effects in transition-metal oxide cells.

Abstract
Novel ballistic electron emission microscopy experiments are reported, aimed to directly visualize and quantify the local inhomogeneities of the effective Schottky barrier height on Au/Nb:SrTiO3 Schottky junctions dominated by interfacial resistance switching effects. The voltage-dependent variation of the local barrier height of the nanometric patches could explain the non-ideal behaviour of the resistance switching effects in transition-metal oxide cells.File in questo prodotto:
