Effective energy-loss functions (EELFs) are derived from experimental reflected electron energy-loss spectroscopy (REELS) spectra measured at different primary energies for copper using an extended Landau approach. The peak profiles of EELFs are between those of the surface and bulk energy-loss functions.

Surface and Interface Analysis, 2003
Abstract Effective energy‐loss functions were derived from the reflection electron energy‐loss spectroscopy (REELS) spectra of Ag by an extended Landau approach. The effective energy‐loss functions obtained are close to the surface energy‐loss function in the low‐energy‐loss region, but tend to be closer to the bulk energy‐loss ...

The energy loss function of the polaron gas
Solid State Communications, 1975Abstract The energy loss function Im 1/ K (π, ω) of a gas of polarons is calculated in the RPA approximation. For typical densities of degenerate polar semiconductors, the energy loss function has pronounced structure. Up to three resonances appear.

Energy-Loss Spectra for High-Energy Electrons as a Function of Depth in an Absorber
Radiation Research, 1969Collimated beams of electrons with energies of 20 and 35 MeV were available from a betatron used for radiotherapy. A semiconductor detector was used to obtain the spectrum of energy deposits by electrons in its 450-jm thickness. The detector was placed behind Lucite to observe the change in spectra with depth. Features of the spectra were compared with

Loss and maintenance of energy-linked functions in aged mitochondria
Biochemical and Biophysical Research Communications, 1970Abstract A number of energy-linked functions were studied in mitochondria aged at 2° for 0–14 days. The stimulation of respiration by ADP, by dinitrophenol (DNP), by Ca++, or by K+ in presence of valinomycin, the ATP-supported active transport of Ca++, and the succinate-induced reversal of the electron flow, disappeared after 2–4 days.

Construction of database of effective energy‐loss functions
Surface and Interface Analysis, 2003Abstract Effective energy‐loss functions for Al, Cu, Ag and Au were derived from the reflection electron energy‐loss spectroscopy (REELS) spectra for 1 keV electrons using extended Landau theory. Features of the obtained effective energy‐loss functions are close to those of optical surface energy‐loss functions, revealing the ...

Energy function for power systems with transmission losses
IEEE Transactions on Power Systems, 1997Stability analysis of nonlinear systems draws heavily on energy functions. For power systems, energy functions have been developed for single machine systems and for the special case of constant power loads and lossless transmission lines, extended to multimachine systems.

Energy-loss function for monolayer phosphorene
Journal of Materials Science, 2018We calculate the energy-loss function for monolayer phosphorene in the framework of time-dependent density functional theory. The calculations are performed in the adiabatic local density approximation with local field effects. We study the origin of the features in the absorption spectra and the energy dispersion of the features in the excitation ...
