“…To a certain extent, this is a reversal of the surface photoeffect. The second idea is related to collective oscillations of the electron gas in the island [10,20,23]. According to this model, the radiation spectrum of an emission center must show resonance bands associated either with electromagnetic decay of a plasmon or with electromagnetic transitions between isolated levels arising from the size quantization of the plasma states in the island [6].…”

Light emission from Ag cluster films excited by conduction current

The light emission spectra obtained for a silver cluster film, excited by the passage of electrical current through it, were measured by the charge‐coupled device (CCD) combined with a monochromator in the spectral range 200 ≑ 1050 nm (6.2 ≑ 1.18 eV). This film is a two‐dimensional ensemble of Ag clusters linked by tunneling on a dielectric substrate. It was shown that the light emission spectra had a number of features, and the shape of spectrum depends on a voltage applied to the film. With increasing the voltage the spectrum starts to extend to high energies. The light emission in the visible spectral region was observed already at 1 V applied to the film, i.e., the photon energy can exceed the excitation energy. It means that this phenomenon is not trivial. In order to explain these results, an assumption about the electron gas heating in metal clusters may be used.

“…For the involved sort of nanoislets (refractory metals or carbon), plasmon decay most probably results in the release of heat, which is necessary in the considered thermoelectric model to maintain the islet's positive potential. (The very possibility of plasmonic oscillations, induced by emission of single electrons by metal islets, has been previously considered, e.g., in publications [27,107]). Electroluminescence from the emission area registered in some experiments can be attributed to electromagnetic decay of the plasmons [106].…”

Low-Field Electron Emission Capability of Thin Films on Flat Silicon Substrates: Experiments with Mo and General Model for Refractory Metals and Carbon

et al. 2021

Herein, we describe a study of the phenomenon of field-induced electron emission from thin films deposited on flat Si substrates. Films of Mo with an effective thickness of 6–10 nm showed room-temperature low-field emissivity; a 100 nA current was extracted at macroscopic field magnitudes as low as 1.4–3.7 V/μm. This result was achieved after formation treatment of the samples by combined action of elevated temperatures (100–600 °C) and the electric field. Morphology of the films was assessed by AFM, SEM, and STM/STS methods before and after the emission tests. The images showed that forming treatment and emission experiments resulted in the appearance of numerous defects at the initially continuous and smooth films; in some regions, the Mo layer was found to consist of separate nanosized islets. Film structure reconstruction (dewetting) was apparently induced by emission-related factors, such as local heating and/or ion irradiation. These results were compared with our previous data obtained in experiments with carbon islet films of similar average thickness deposited onto identical substrates. On this basis, we suggest a novel model of emission mechanism that might be common for thin films of carbon and refractory metals. The model combines elements of the well-known patch field, multiple barriers, and thermoelectric models of low-macroscopic-field electron emission from electrically nanostructured heterogeneous materials.
