英文摘要	An intrinsic mechanism of photoinduced hole transfer reactions occurring at the grapheme-PbS interface is described with the purpose of building a tunable photosensor with a responsivity of more than 10(3) A W(-1) . It is remarkable that rational utilization of this finding also realizes symmetric, opposing photoswitching effects, which are effectively mirror images, in a single pristine graphene device. These results highlight the vital importance of interface modification as a powerful tool for creating future ultrasensitive optoelectronic devices.Copyright ? 2012 WILEY-VCH Verlag GmbH & Co.
