Abstract

Two sets of ZnO ultraviolet photodetectors were fabricated on the quartz and sapphire, respectively. Because of the different lattice matching of the substrate for the ZnO, the ZnO thin film based on the high matching substrate has a better crystalline quality and it is more sensitive to ultraviolet light. The ultraviolet photodetector based on the sapphire not only has a stronger absorption for the light, but also has a higher photo response than the ultraviolet photodetector based on the quartz. Which will have a profound influence for fabricating the excellent photodetectors.
