Electronic excitation spectrum of doped organic thin films investigated using electron energy-loss spectroscopy
The electronic excitation spectra of undoped, and potassium as well as calcium doped phenantrene-type hydrocarbons have been investigated using electron energy-loss spectroscopy (EELS) in transmission. In the undoped materials, the lowest energy excitations are excitons with a relatively high binding energy. These excitons also are rather localized as revealed by their vanishing dispersion. Upo...
متن کاملElectronic excitation of furfural as probed by high-resolution vacuum ultraviolet spectroscopy, electron energy loss spectroscopy, and ab initio calculations.
The electronic spectroscopy of isolated furfural (2-furaldehyde) in the gas phase has been investigated using high-resolution photoabsorption spectroscopy in the 3.5-10.8 eV energy-range, with absolute cross section measurements derived. Electron energy loss spectra are also measured over a range of kinematical conditions. Those energy loss spectra are used to derive differential cross sections...
متن کاملElectron energy-loss spectrum-imaging
Electron energy-loss spectroscopy (EELS) in the scanning transmission electron microscope (STEM) is a powerful method for analyzing elemental, chemical, dielectric, and other information. The technique can be extended to produce quantitative images useful for interpreting the spatial distribution of this information. This paper describes an implementation of a new method of quantitative mapping...
متن کاملElectron energy-loss spectroscopy study of ZnO nanobelts.
Nanobelts of ZnO have well-defined shapes that are enclosed by {0001}, {0110} and {2110} facets. The nanobelts grow along [0110] and [2110] with large flat surfaces of +/-(0001) and +/-(0110), respectively. Electron energy-loss spectroscopy has been applied to study the electronic structure of ZnO nanobelts of different growth orientations. A plasmon peak observed at 13 eV is suggested to be th...
متن کاملFundamentals of electron energy-loss spectroscopy
Electron energy-loss spectroscopy (EELS) is an analytical technique that is based on inelastic scattering of fast electrons in a thin specimen. In a transmission electron microscope (TEM) it can provide structural and chemical information about a specimen, even down to atomic resolution. This review provides an overview of the physical basis and new developments and applications of EELS in scan...
