Origin of the photoemission final-state effects in Bi2Sr2CaCu2O8 by very-low-energy electron diffraction

, 2003
Very-low-energy electron diffraction with a support of full-potential band calculations is used to achieve the energy positions, K// dispersions, lifetimes and Fourier compositions of the photoemission final states in Bi2Sr2CaCu2O8 at low excitation ...

In-situ Investigation of the Early Stage of TiO2 epitaxy on (001) SrTiO3 [PDF]

, 2011
We report on a systematic study of the growth of epitaxial TiO2 films deposited by pulsed laser deposition on Ti-terminated (001) SrTiO3 single crystals. By using in-situ reflection high energy electron diffraction, low energy electron diffraction, x-ray

Instrumentation for low-energy electron diffraction [PDF]

Review of Scientific Instruments, 1983
Recent developments in instrumentation for low-energy electron diffraction (LEED) are reviewed. After a summary of the major types of measurements in LEED, the properties of LEED instruments that are important in performing these measurements are described. A detailed discussion is presented on the major components of a LEED diffractometer.

Experimental Determination of Electron Transition Probabilities in Elementary Electron-Phonon Scattering Processes Using Electron-Energy-Loss Spectroscopy: The Example of Graphite

, 2010
We have investigated coupling constants in elementary electron-phonon scattering processes on a graphite surface by the combined use of high-resolution electron-energy-loss spectroscopy (HREELS) and very low-energy electron diffraction (VLEED). HREELS is

Direct Detection Electron Energy-Loss Spectroscopy: A Method to Push the Limits of Resolution and Sensitivity

Scientific Reports, 2017
In many cases, electron counting with direct detection sensors offers improved resolution, lower noise, and higher pixel density compared to conventional, indirect detection sensors for electron microscopy applications.

Twins and their boundaries during homoepitaxy on Ir(111)

, 2010
The growth and annealing behavior of strongly twinned homoepitaxial films on Ir(111) has been investigated by scanning tunneling microscopy, low energy electron diffraction and surface X-ray diffraction. In situ surface X-ray diffraction during and after

A new structural model for the Si(331)-(12x1) reconstruction [PDF]

, 2008
A new structural model for the Si(331)-(12x1) reconstruction is proposed. Based on scanning tunneling microscopy images of unprecedented resolution, low-energy electron diffraction data, and first-principles total-energy calculations, we demonstrate that

An approach to surface electron density-sensing property correlation in non-stoichiometric boron carbide

AIP Advances
The key to most surface phenomena lies in the surface electron density. Particularly, it is the electron density distribution over the surface that primarily controls the overall interaction of the material with the external environment, say in processes

Direct observation of the atomic density fluctuation originating from the first sharp diffraction peak in SiO2 glass

NPG Asia Materials
The intermediate-range order of covalently bonded glasses has been extensively studied in terms of their diffraction peaks observed at low scattering angles; these peaks are called the first sharp diffraction peaks (FSDPs).
