Performance Enhanced Photoconductive Channels Based on (Carbon Nanotube)-(CdS Nanowire) Hybrid Nanostructures

ORAL

Abstract

Previous researches showed that the performance of photoconductive channels based on individual CdS \textit{nanowires} (NWs) is improved compared to the CdS \textit{bulk} or \textit{thin-film}-based channels. However, the assembly of a single NW is usually complex and time-consuming. Herein, we report a high-performance photoconductive channel based on CNT--CdS NW hybrid nanostructures, which can be easily prepared on both flat and curved substrates. In our experiments, the CNT-network-based channel was fabricated using a directed assembly method. We found that our channels exhibited much larger photocurrent and faster photoresponse than those of previously reported CNT or CdS NW-based channels. In addition, we fabricated the channels on a curved surface.
