Abstract

Zinc oxide single crystals with a high percentage of exposed 4 2-2-3- reactive facet were prepared by a facile hydrothermal route. X-ray diffraction, field emission scanning electron microscopy, and high resolution transmission microscopy confirmed the faceted single crystal structure. Through the density functional theory (DFT) calculations, it is validated that the 4 2-2-3- surface of ZnO crystals has high surface energy. When used as a sensing material in gas sensors, ZnO crystals with dominating exposed 4 2-2-3- planes exhibited a superior sensitivity toward toxic and flammable gases.
