New Electron Spectroscopy Findings Has Been Reported by S.A. Nepijko et al (Investigation of a Ge nanoparticle film by means of electron stimulated photon emission spectroscopy)

By a News Reporter-Staff News Editor at Journal of Technology -- Research findings on Electron Spectroscopy are discussed in a new report. According to news originating from Berlin, Germany, by VerticalNews correspondents, research stated, "Electron stimulated photon emission spectroscopy was used for the study of the electronic structure of Ge nanoparticles. A nanoparticle film was prepared by thermal deposition on a quartz substrate."

Our news journalists obtained a quote from the research, "Photon emission was stimulated by electron bombardment at energies of several hundred electron volts. Electron field emission from a W-tip was used at tip voltage U-t = 100-600 eV. A spectrometer in combination with a liquid nitrogen cooled charge-coupled device (CCD) camera was used for light detection. Light emission spectra were measured in the energy range 1.18-4.2 eV. They are characterized by features at similar to 1.6 and similar to 3.1 eV."

According to the news editors, the research concluded: "A comparison with light emission spectra obtained with another excitation, i.e. by applying a voltage of U-f = 2 V to the Ge nanoparticle film gives further insight into the mechanism of photon emission."
