Researchers from University of Surrey Describe Findings in Science and Technology

June 24, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Science and Technology are presented in a new report. According to news reporting originating from Guildford, United Kingdom, by VerticalNews correspondents, research stated, "The fabrication of highly functional materials for practical devices requires a deep understanding of the association between morphological and structural properties and applications. A controlled hydrothermal method to produce single crystal ZnO hexagonal nanodisks, nanorings, and nanoroses using a mixed solution of zinc sulfate (ZnSO4) and hexamethylenetetramine (HMTA) without the need of catalysts, substrates, or templates at low temperature (75 C) is introduced."

Our news editors obtained a quote from the research from the University of Surrey, "Metal-semiconductor-metal (MSM) ultraviolet (UV) detectors were fabricated based on individual and multiple single-crystal zinc oxide (ZnO) hexagonal nanodisks. High quality single crystal individual nanodisk devices were fabricated with inkjet-printed silver electrodes."

According to the news editors, the research concluded: "The detectors fabricated show record photoresponsivity (3300 A/W) and external quantum efficiency (1.2 x 10(4)), which we attribute to the absence of grain boundaries in the single crystal ZnO nanodisk and the polarity of its exposed surface."
