Abstract EN
Spin-coating photoresist film on ZnO nanowire (NW) was introduced into the fabrication procedure to improve photoresponse and recovery speed of a ZnO NW ultraviolet photoelectric detector.
A ZnO NW was first assembled on prefabricated electrodes by dielectrophoresis.
Then, photoresist was spin-coated on the nanowire.
Finally, a metal layer was electrodeposited on the nanowire-electrode contacts.
The response properties and I-V characteristics of ZnO NW photodetector were investigated by measuring the electrical current under different conditions.
Measurement results demonstrated that the detector has an enhanced photoresponse and recovery speed after coating the nanowire with photoresist.
The photoresponse and recovery characteristics of detectors with and without spin-coating were compared to demonstrate the effects of photoresist and the enhancement of response and recovery speed of the photodetector is ascribed to the reduced surface absorbed oxygen molecules and binding effect on the residual oxygen molecules after photoresist spin-coating.
The results demonstrated that surface coating may be an effective and simple way to improve the response speed of the photoelectric device.
