Colloidal chemically fabricated ZnO : Cu-based photodetector with extended UV-visible detection waveband.

چکیده
Polycrystalline ZnO : Cu-based film photodetectors with extended detection waveband (UV and visible light) were fabricated using facile colloidal chemistry and a post-annealing process. The obtained detectors are highly sensitive to visible light and can realize the response switch between UV and visible light. A native and extrinsic trap cooperatively controlled space charge limited (SCL) transport mechanism is proposed to understand this complex photoconduction behaviour.

متن کاملPiezo-phototronic effect enhanced visible and ultraviolet photodetection using a ZnO-CdS core-shell micro/nanowire.
The piezo-phototronic effect is about the use of the piezoelectric potential created inside some materials for enhancing the charge carrier generation or separation at the metal-semiconductor contact or pn junction. In this paper, we demonstrate the impact of the piezo-phototronic effect on the photon sensitivity for a ZnO-CdS core-shell micro/nanowire based visible and UV sensor. CdS nanowire ...

Electrochemical deposition (ECD) is a versatile technique for the preparation of ZnO nanowires (NWs) and nanorods (NRs) with high structural and optical quality. The bandgap of the ZnO NWs can be engineered by doping. Depending on the doping cation and concentration, the bandgap is increased or decreased in a controlled manner. The NW arrays have been grown on various substrates. The epitaxial ...
