Fabrication of ZnO Nanowires Using Nanoscale Spacer Lithography for Gas Sensors

Sensitive nanowires: ZnO nanowire arrays are fabricated by nanoscale spacer lithography, a top‐down paradigm consisting of photolithography, ZnO atomic‐layer deposition, and low‐damage dry etching. ZnO nanowire devices based on this technique (see picture) show good electrical transport and gas‐sens...

Summary:Sensitive nanowires: ZnO nanowire arrays are fabricated by nanoscale spacer lithography, a top‐down paradigm consisting of photolithography, ZnO atomic‐layer deposition, and low‐damage dry etching. ZnO nanowire devices based on this technique (see picture) show good electrical transport and gas‐sensing properties to various concentrations of H2 and CO.
