Fabrication of ZnO Nanowire Devices via Selective Electrodeposition

We introduce a solution-based electrodeposition technique that selectively deposits copper only at the contacts between nanowires/nanobelts/nanotubes and the electrodes, while leaving the device surfaces clean. This was achieved using a copper nitrate bath with low covering power. Our method demonstrates an effective, parallel process for achieving stable electric and mechanical contacts for one-dimensional nanomaterial-based devices on a large scale.
