Cooling metals via gap plasmon resonance
WebJan 5, 2009 · Gap plasmon-polariton (GPP) nanoresonators based on a metal nanostrip separated with a small gap from a metal surface or metal block are considered. Scattering resonances and field enhancements are studied for two-dimensional structures using the Green's-function surface integral equation method (GFSIEM). For small gaps, we show … WebJun 24, 2024 · The trimer plasmon is now treated as a combination of two gap plasmons. In our picture, the new plasmons are formed by the hybridization of these gap plasmons. The gap plasmons are strongly confined in their respective gaps and all of the gaps are well separated, meaning that the gap plasmons do not overlap significantly.

WebWhen the GST film is in an amorphous state, plasmon resonance occurs at the interface between the top surface of the underlying metal and GST, and the same resonance phenomenon is also excited at the interface between the top gold array and the nano-spaced Al 2 O 3 layer. In addition, since the thickness of the dielectric layer is changed … WebNov 21, 2013 · From Fig. 3, it can be seen that stronger plasmon resonance occurs as the gap width becomes smaller. Consequently, the enhancement effect due to graphene increases with decreasing gap width. The charge response of the graphene and the metal may also affect plasmon resonance in the metal structures. 26 26. J.

WebWe report highly emissive and radiatively cooled metallic surfaces that sustain multiple and high-amplitude gap plasmon cavity modes within the principal thermal radiation spectrum at room temperature (i.e., 8–13 μm).
WebA gap surface plasmon (or gap plasmon) is a guided electromagnetic wave which propagates in a transparent medium located between two extremely close metallic regions. Propagating in a gap between metals forces light to propagate partially inside the metallic regions, causing the gap plasmon to slow down..
