Hydrogen gas sensing properties of WO3 sputter-deposited thin films enhanced by on-top deposited CuO nanoclusters

2018-11-24 | Tomáš Duchoň

The advent of the hydrogen economy is accompanied by increased demand for sensing devices. In our recent paper, we introduce an improvement of WO3-based hydrogen sensors via deposition of CuO nanoclusters that lead to the formation of nano p–n junctions on the surface. The preparation techniques used in the study are scalable and compatible with standard industrial processes. Furthermore, the improvement was achieved without the use of noble metals.
