Studies in the Area of Zinc Oxide Nanotechnology Reported from Hong Kong University of Science and Technology

March 7, 2014



By a News Reporter-Staff News Editor at Science Letter -- Research findings on Nanotechnology are discussed in a new report. According to news reporting originating from Hong Kong, People's Republic of China, by NewsRx correspondents, research stated, "We propose hydrogen peroxide (H2O2) solution as a novel and promising etchant for ZnO thin film with well-controlled etching performances and enhanced ultraviolet (UV) luminescence, which is also facile, inexpensive and environmentally friendly. We have analyzed its etching mechanism and surface modification effect for ZnO."

Our news editors obtained a quote from the research from the Hong Kong University of Science and Technology, "Using this etchant, fine patterns have been transferred to the ZnO single-crystal films with good fidelity. The etching performances have been comprehensively investigated using Raman spectroscopy, scanning electronic microscopy (SEM), atom force microscopy (AFM), surface profiler and photoluminescence (PL) spectrometer."

According to the news editors, the research concluded: "The results have shown that ZnO films after the long-time etching exhibited linear etching rate, smooth profile and increased UV emission, which enables H2O2 solution as an excellent wet etchant for various ZnO-based optoelectronic devices."
