External electron emission near nanocylinders

Photoemission spectroscopy of planar and nanostructured surfaces

“…As it can be seen from the equations and the figure, the electron contribution is strongly dominating over the hole contribution, in surface plasmon production. This phenomenon was observed previously [34] and can be attributed to the fact that once the electron is released, it interacts with the electron gas inside the cylinder for a long time.…”

“…The analysis of the obtained electron spectra usually uses this model [18] and the separation of the plasmon production into extrinsic and intrinsic contributions [19][20][21][22]. However these criteria are not always accu-rate, as in the case when the electron-hole pair is created near the surface, or for nanosized systems [23].…”

Surface plasmons induced in Al spherical nanoparticles by Auger effect

“…In previous works we studied extensively the surface plasmon production process due to electron-hole interaction applying both semi-classical and quantum mechanical models, and have found a three-term expression for the plasmon contribution [7][8][9][10].…”

Quantum Mechanical Model for Plasmon Excitations in Nanostructures

“…Usually, the study of plasmon excitations in solids is dealt by means of the dielectric model for which all the electrical properties of the material are contained in a function of the angular frequency ω and the wave number k, known as the dielectric function . This model is very appropriate and suitable when the number of atoms in the nanostructure is enough to make a clear distinction between the surface and the volume [16][17][18][19][20]. But it takes no account for the local fields resulting from the electronic density fluctuations and their interaction with the ionic lattice, phenomena which were advised earlier [21][22][23][24][25][26][27][28][29][30].…”
