Abstract

We examine 10 nm thick film structures containing either Hf or Ti sandwiched between two respective oxide layers.The layers are deposited onto heated substrates to create a diffusion region.We observe a high degree of light sensitivity of the electric current through the film thickness for one polarity of an applied voltage. For the other polarity, the current is not affected by the light. We explain the observed phenomenology using the single-particle model based on the existence of interface states on the metal-oxide interfaces.
