报告人简介:
Alexey V. Krasavin received his B.Sc. (with honours) and M.Sc. (with honours) degrees from Moscow Institute of Physics and Technology. In 2006, he was awarded a Ph.D. degree in Physics from the University of Southampton and joined Queen’s University Belfast as a Research Fellow. Since 2010 he works at King’s College London. His research interests include active manipulation of light at the nanoscale, nonlinear plasmonic-assisted effects, plasmonic-enhanced fluorescence, nonlocal and quantum phenomena.
报告摘要：
Two-dimensional single-crystal metals are highly sought after for next-generation technologies. In my talk I will report large-area, single-crystal two-dimensional gold with thicknesses down to a single-nanometer level, employing an atomic-level-precision chemical etching approach. The ultrathin thickness and single-crystal quality endow two-dimensional gold with unique properties including significantly quantum-confinement-augmented optical nonlinearity, low sheet resistance, high transparency and excellent mechanical flexibility. This will be demonstrated on the examples of the use of ultrathin gold nanoflakes for low-loss nanocavity plasmonics and highly enhanced nonlinear optical effects.
