Plasmon-Enhanced Photoresponse of a Single Silver Nanowire and its Networked Gadgets


Picture-bolometric impact is critically essential in optoelectronic constructions and units using metallic electrodes with nanoscale options as a consequence of heating attributable to the plasmonic discipline enhancement. One peculiar case is particular person silver nanowires (Ag NWs) and their networks. Ag NW-networks exhibit glorious thermal, electrical, and mechanical properties, offering a easy but dependable various to widespread versatile clear electrode supplies utilized in optoelectronic units. To this point there have been no reviews on the photoresponse of Ag NWs. On this work, we present {that a} single Ag NW and a community of such Ag NWs possess a major, intrinsic photoresponse because of the photo-bolometric impact, as immediately noticed and measured utilizing scanning photocurrent microscopy. Floor plasmon polaritons (SPP) created on the contact metals or plasmons created on the nanowire-metal constructions trigger heating on the junctions the place a plasmonic discipline enhancement is feasible. The native heating of the Ag NWs ends in detrimental photoconductance as a result of bolometric impact. Right here an open-circuit response as a result of plasmon-enhanced Seebeck impact was recorded on the NW-metal contact junctions. The SPP-assisted bolometric impact is discovered to be additional enhanced by adorning the Ag NWs with Ag nanoparticles. These observations are related to using metallic nanowires in plasmonic purposes specifically and in optoelectronics basically. Our findings could pave the trail for plasmonics enabled sensing and not using a spectroscopic detection.
