To increase the photodetectivity, we design an Ag nanocube nanoresonator with a strong gap-plasmon resonance in the visible range to further enhance the photoresponsivity by engineering the optical response for the NbN superconducting devices. This is due to the superconducting states are broken down by a localizing strong electromagnetic field. To design the plasmonic nanostructures, we calculated the electromagnetic field distribution of Ag nanocube/Al2O3/NbN structure by finite-difference time-domain (FDTD). We observed a strong plasmonic resonance field which tightly confined in the Al2O3 layer between the Ag nanocube and NbN film at a resonant wavelength of 532 nm. In the end, we will also discuss the detailed working mechanism and the potential application of plasmon-enhanced photodetection in NbN superconducting photodetectors.","PeriodicalId":118068,"journal":{"name":"Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123529514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the hybrid configuration, optical absorption is found to be evidently increased, indicating the availability of optical pumping fluences is prominently improved. Meanwhile, rugged film morphology and the corresponding chemical reaction are also observed and further investigated. Besides, by conducting a series of temperature-dependent cryogenic and a systematic power-dependent micro-PL measurement with different excitation wavelengths, the relationship in wavelength positions between each other can be validated, confirming the mechanism for the enhancement on light emission performance. Finally, for a such hybrid configuration, the corresponding randomlasing performance is found can be enhanced by a factor of three.","PeriodicalId":118068,"journal":{"name":"Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124841828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These exhibit record-high field confinement, squeezing light down to nanometer dimensions. Hence, plasmons in such heterostructures make ideal candidates to probe the quantum nonlocal electrodynamic response of the nearby metal. We treat graphene at the level of the RPA and describe the nonclassical optical response of the metal using a framework of mesoscopic electrodynamics based on microscopic surface-response functions, known as Feibelman d-parameters, which embody quantum corrections in the metal’s response. We show that the graphene plasmons’ resonances exhibit quantum shifts due to the quantum surface-response of the metal, and show how these spectral shifts can be used to interrogate the quantum surface-response of metals, thus provide a theoretical basis for experimentally inferring the said quantum surface-response.","PeriodicalId":118068,"journal":{"name":"Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115528698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
