摘要：

We report on the significant generation of photocurrent (PC) from planar devices built from the drop casting of UV-laser-synthesized single-wall-carbon-nanotubes (SWCNTs) onto n-Si substrate. These SWCNTs/n-Si hybrid devices are shown to generate PC with external quantum efficiencies (EQE) reaching up to similar to 10%. Their EQE has been optimized by controlling the amount of deposited SWCNTs, and is shown to be significantly enhanced over all the spectral range with a pronounced boost (up to similar to 25X times) around 460 nm. The extension of the photoresponse of these devices toward UV correlates well with the absorbance of SWCNTs. (C) 2010 American Institute of Physics. [doi:10.1063/1.3513266]
