Thermionic emission in gold nanoparticles under femtosecond laser irradiation observed with photoemission electron microscopy
This study reports that thermionic emission can dominate over multi-photon ionization in gold nanoparticles under femtosecond laser irradiation. The brightness of individual particles observed with photoemission electron microscopy increased steeply for laser power above 200 mW, which is reproduced...
