Abstract:

Zinc oxide single crystals with a high percentage of exposed {4 2̄ 2̄ 3̄} 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 2̄ 2̄ 3̄} surface of ZnO crystals has high surface energy. When used as a sensing material in gas sensors, ZnO crystals with dominating exposed {4 2̄ 2̄ 3̄} planes exhibited a superior sensitivity toward toxic and flammable gases. © 2013 Elsevier B.V.
