WebFeb 4, 2024 · Sharp optical resonances in high-index dielectric nanostructures have recently attracted significant attention for their promising applications in nanophotonics. … As examples, several Fano resonances in the extreme ultraviolet photoionization spectrum of neon are attributed to autoionizing states. Some are due to one-electron excitations, such as a series of three strong similarly shaped peaks at energies of 45.546, 47.121 and 47.692 eV which are interpreted as 1s 2s 2p np ( P) states for n = 3, 4 and 5. These states of neutral neon lie beyond the first ionization energy because it takes more energy to excite a 2s electron than to remove …
