Metal oxide semiconductor gas sensors have been widely studied for the selective detection of various gases with trace concentrations. The identification of the reaction scheme governing the gas sensing response is crucial for further development; ho

Polarity-controlled epitaxial ZnO films with two types of surface morphologies were prepared using pulsed laser deposition, and their gas sensing responses to several reductive gases were determined. Gas response measurements of high-temperature-grow

To examine the effect of Mg addition on the gas sensing properties of ZnO, MgxZn1-xO epitaxial films with a constant thickness, in-plane crystal grain size, and surface morphology and varying Mg contents were prepared by pulse laser deposition, and t

We report synthesis and excitonic emission properties of high-quality micrometer-thick $\mathrm{M}{\mathrm{g}}_{x}\mathrm{Z}{\mathrm{n}}_{1\ensuremath{-}x}\mathrm{O}$ films ($x=0.04$ and 0.10) grown on $a$-sapphire substrates by pulsed laser depositi

Films of ZnO have been implanted with fluxes of Co and Eu ions so as to give a layer of Zn0.96Co0.04O or Zn0.96Eu0.04O or Zn0.92Co0.04Eu0.04O that is approximately 15 nm thick. The ZnO films were deposited by pulsed laser deposition and had an O-pola

The floating zone method was used to obtain single crystals several mm in size of the low-temperature rhombohedral form of Y2C rather than its typical rocksalt-type cubic form. This was achieved through optimization of the chemical compositions of th

Low-energy He+ ion scattering spectroscopy (He+ LEIS) was combined with the pulsed jet technique to analyze the outermost surface of a Zn-ZnO (0 0 0 1) substrate that is sensing trace ethanol (EtOH, 50 ppmv) contained in the air. The gas sensing resp
