Long-lived modulation of plasmonic absorption by ballistic thermal injection

Nature Nanotechnology, Published online: 09 November 2020; doi:10.1038/s41565-020-00794-z

An energy transduction mechanism across metal/semiconductor interfaces, which relies on electron-electron energy transfer rather than the transport of charge, is demonstrated through ultrafast infrared spectroscopy. This ballistic thermal injection process allows for extended modulation of plasmonic absorption in epsilon-near-zero media.
