Near-field light emission from nano- and micrometric complex structures

Near-field light emission from nano- and micrometric complex structures

We propose a general theoretical scheme for the investigation of light emitted from nanoand micrometric structures of arbitrary shape and composition. More specifically, the proposed fully three-dimensional approach allows to derive the light-intensity distributions around the emitting structures and their modifications in the presence of nearby scattering objects. Our analysis allows to better...

Field emission from nano-cluster carbon films

Field emission has been reported to occur at much lower fields in carbon based thin film systems than from any other material systems. The emission has been shown to depend on the various material parameters, but whichever carbon based system is used, it is found that emission occurs at localised sites rather than uniformly over the entire surface. Carbon films with mixed sp3 sp2 bonding, like ...

Emission, scattering and localization of light in complex structures: From nanoantennas to disordered media

Field Emission Microscopy, Spectroscopy,Scanning Electron Microscopy and Field Emission Phenomena from Graphene-like Structures

The presented paper gives a general overview of studies of field emission from carbon nanoclusters. The special attention has been given to the study of emission processes in the strong and super strong electric fields from graphene-like structures. The direct experiments have confirmed the phenomena of the low threshold field emission and explosive emission from carbon nanoclusters. Experiment...

Gamma-Ray emission from SN2014J near maximum optical light

Context. The optical light curve of Type Ia supernovae (SNIa) is powered by thermalized gamma-rays produced by the decay of Ni and Co, the main radioactive isotopes synthesized by the thermonuclear explosion of a C/O white dwarf. Aims. Gamma-rays escaping the ejecta can be used as a diagnostic tool for studying the characteristics of the explosion. In particular, it is expected that the analysi...
