Zotev, Xuerong Hu, Alexander J. Knight et al.arXiv·2023·10.1021/acsnano.4c02178·arXiv:2304.02537AbstractDielectric nanoresonators can reduce optical losses while retaining strong confinement when combined with metals. This work fabricates and characterizes WS₂ nanoantennas on gold substrates, observes hybridized Mie-plasmonic resonances and supercavity behavior, and uses electromagnetic simulations to predict field enhancement and Purcell factors for WS₂ nanoantennas on gold with an hBN spacer.Read more
