英文摘要: Abstract(#br)Photo-corrosion is a common phenomenon observed in the photocatalytic semiconductor materials, which can seriously harm the photoelectric properties and performances in the energy applications. However, in this paper, we demonstrated that the photo-corrosion effects can be used for the microfabrication of conductive structures on a photocatalytic film like zinc oxide (ZnO), named as “photoetching”. Our results demonstrated that microstructures can be prepared within seconds with a precision at an order of tens of micrometers using our current devices. Different from the previous work, the etching process was achieved free of conducting layer under the ZnO film, avoiding the short-circuit of the conductive micro-patterns and enabling the use for the impedance sensing. We...
