The project deals with basic research of oxidic heterojunctions used in chemiresistors, which are intended for detection of gases. It introduces an innovative approach in the combination of: (a) preparation of sensitive layer using low energy ion beams and/or hydrothermal growth, (b) characterization techniques that enable to characterize electric charge transport in individual heterojunctions at the nanoscale, (c) advanced characterization of sensor components consisting of these individual heterojunctions and (d) utilizing heterojunctions with a reversible change of oxidic phases acting as gas-dose counters. Moreover, the project employs recently developed growth and deposition techniques within the research team that will allow to precisely control the properties of the nanostructures. The project goal is to correlate the phenomena taking place in individual nano heterojunctions and external characteristics of the sensor element.
