Rezumat

In this work, an individual zinc oxide (ZnO) nanosheet was integrated into a sensor device for detection of UV light with ultra-high photosensitivity. Three-dimensional (3-D) and two-dimensional (2-D) highly porous ZnO micro- and nanostructures networks were synthesized via a simple oxidation of Zn metal powder in a furnace. The ultra-high photosensitivity (IUV/Idark ~ 220) of the individual ZnO nanosheet was explained based on to the dominance of the polar (0001) surfaces and the adsorption and desorption of the ambient gas molecules on these surfaces.
