“…Here, a cos(θ) 6 simulation fits well with the experimental data, pointing to a nonlinear three photon absorption process. This is the minimum number of photons to overcome the work function of Au, whose expected value lies in the interval [4.9 and 5.5 eV] . Computed field distribution map and in-plane rotation dependence support this result (Figure b,d).…”

We present a new method to pattern assemblies of gold nanorods (GNRs) on substrates and a study of the near-field coupling induced by the aggregation of the nanoparticles. The combination of deep-UV lithography and controlled deposition of functionalized GNRs generates complex GNR assemblies. Near-field coupling is investigated by photoemission electron microscopy (PEEM) on single, dimer, and elongated aggregates of GNRs. This comparative study exhibits different kinds of near-field coupling efficiency that occur depending of the incident light polarization, interparticle gaps and angles between the nanorods. Hot spots of the near-field are associated with the interparticle gap regions.

“…Cadmium selenide is interesting as a material with a band gap comparable to the photon energy of visible light (1.7-1.8 eV). There are a large number of works, which describe the electronic properties of quantum dots based on CdSe nanoparticles, which can be used as elements of high-resolution optical systems [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] . In particular, X-ray diffraction analysis indicates [15] that the structure of CdSe nanoparticles with sizes of 2.8 nm, 4.1 nm and 5.6 nm is wurtzite-like, and the energy gaps E gap for these particles are 2.5 eV, 2.2 eV, and 2.0 eV, respectively.…”

The authors fulfilled calculations of the total energy and electronic states of CdnSen nanoparticle:“wurzite”, “sphalerite” and “rock-salt” types of the structure. It was shown that at n ≤ 72 the “rock-salt” type is the most favorable energetically. However the extrapolation of the behavior of the energy per Cd-Se atomic pair shows that for n > 130 (corresponding to a size of about 2 nm), particles with a “wurtzite” structure can be more advantageous. Particles of the “wurtzite” and “rock-salt” types have an electronic structure with an energy gap. For particles with the “wurtzite”structure, the gap width decreases with increasing particle size: from 3.3 eV to 2.2 eV as the particle increases from 0.5 nm to 1.5 nm. For particles of the “rock-salt” type, the gap width grows slightly, remaining about 3 eV.“Sphalerite”-type particles have a metal-like electronic structure.

Electron field emission is a complicated phenomenon which is sensitive not only to the particular material under illumination but also to the specific crystalline orientation of the surface. Summarizing the ability for a crystal to emit in a particular direction would be of great use when searching for good field emitters. In this paper we propose a material normal energy distribution which describes the ability of the bound electrons to tunnel under an intense electric field. This framework breaks a computationally expensive 3-D system down to a source distribution representation applicable for more efficient 1-D models. We use the Fowler-Nordheim framework to study the yield and MTE (mean transverse energy) from sources including gold, copper, and tungsten in both monocrystalline and polycrystalline forms. We find an increase in effective work function for field emission in the (111) direction for gold and copper associated with the Bragg plane intersections of the Fermi surface.
