Scalable integration of indium zinc oxide/photosensitive-nanowire composite thin-film transistors for transparent multicolor photodetectors array.

By incorporating crystalline photosensitive nanowires (NWs), an amorphous InZnO (a-IZO) thin film is designed to be sensitive to the primary colors of light via a facile sol-gel approach. The mobility is also improved. The composite devices leverage the advantages of the transparency of a-IZO with the photosensitivity of CdS NWs.
