New data on ultrafast electron photoemission from metallic nanostructures obtained

Metallic nanoparticle ensembles are capable of emitting short bunches of electrons when irradiated by powerful laser pulses of femtosecond (1 fs = 10-15 s) duration. Scientists at Lobachevsky University have long been studying the plasmon effect -- the excitation by light of collective electron oscillations in nanoparticles and the amplification of the light field associated with these oscillations in the vicinity of the nanoparticle, which plays the main role in this process.
