Enhanced photoemission from laser-excited plasmonic nano-objects in periodic arrays

Original language description

The process of photoelectron emission from gold surfaces covered with objects that are organized in the form of a periodic array is addressed in the short laser pulse regime at moderate intensities and for various laser wavelengths. The emission spectrum from a gold single crystal measured under the same conditions is used for reference. The comparison of the photo-emission yield and the energy of the ejected electrons with their counterparts from the (more simple) reference system shows that the periodic conditions imposed on the target surface drastically enhance both quantities. In addition to the standard mechanism of Coulomb explosion, a second mechanism comes into play, driven by surface plasmon excitation. This can be clearly demonstrated by varying the laser wavelength. Despite the fact that the incident laser intensity is as low, such a structured target permits generating electrons with energies as high as 300 eV.
