Paper Abstract

The thin film technology is used to intentionally combine functional properties of metal oxides at the nanoscale. An ultra thin construction of metal oxide layers is sandwiched between the metal contacts and a system with the gas sensitivity is made and characterized. The built in potential differences in the construction results a combination of the photovoltaic effect and the electrical response to the gas-surface interaction. The response is detected at the ambient temperature, it is sufficiently fast for the practical purposes and is reversible without and with assistance of light even if the response memristance exists. The parameters of the sensor can be intentionally modified by the thin film technology.
