英文摘要 | We demonstrate a strong photocurrent enhancement in carbon nanotube (CNT) photodetectors by coupling the CNT with a plasmonic nanostructure made of Au nanoparticles. Comparing with the device without coupling to Au nanoparticles, more than 3 times photocurrent enhancement is observed and attributed to the strong local field enhancement on the CNT. The plasmonic near-field coupling with CNTs with different diameters is also investigated and the results suggest that CNTs with larger diameter show stronger enhancement. This work demonstrates the potential to significantly improve the performance of CNT photoelectric devices using metallic nanoparticles that support surface plasmons.
