Abstract EN
We demonstrate ZnO nanowire based UV sensor by laser-induced hydrothermal growth of ZnO nanowire.
By inducing a localized temperature rise using focused laser, ZnO nanowire array at ~15 μm size consists of individual nanowires with ~8 μm length and 200~400 nm diameter is readily synthesized on gold electrode within 30 min at the desired position.
The laser-induced growth process is consecutively applied on two different points to bridge the micron gap between the electrodes.
The resultant photoconductive ZnO NW interconnections display 2~3 orders increase in the current upon the UV exposure at a fixed voltage bias.
It is also confirmed that the amount of photocurrent can be easily adjusted by changing the number of ZnO NW array junctions.
The device exhibits clear response to the repeated UV illumination, suggesting that this process can be usefully applied for the facile fabrication of low-cost UV sensor array.
