p-ZnO nanowires—A promising material for the fabrication of vacuum pressure sensors

The fabrication of a vacuum pressure sensor on the basis of p -ZnO nanowires is described. The nanowires are grown by electrodeposition from an aqueous solution in an electrochemical cell with two electrodes. It is assumed that the hole conductivity in the nanowires is caused by the zinc vacancy V Z...

Description
Summary:The fabrication of a vacuum pressure sensor on the basis of p -ZnO nanowires is described. The nanowires are grown by electrodeposition from an aqueous solution in an electrochemical cell with two electrodes. It is assumed that the hole conductivity in the nanowires is caused by the zinc vacancy V Zn . The operation basis of the fabricated vacuum pressure sensor is the oxygen chemisorption-desorption process on the surface of ZnO nanostructures. It is shown that the current flowing through the p -ZnO nanostructures in the fabricated vacuum pressure sensor linearly increases with pressure in semilogarithmic coordinates.
