Radiation attenuation properties based on the quantification of soil components using the Rietveld Method

Results in Physics, 2019
We propose the use of X-ray diffraction associated with Rietveld Method (RM-XRD) for soil components quantification aiming at evaluating photon attenuation parameters (total and partial attenuation coefficients (µ), effective atomic number (Zeff ...

In situ reflection electron energy loss spectroscopy measurements of low temperature surface cleaning for Si molecular beam epitaxy [PDF]

, 1993
In situ analysis of hydrocarbon desorption from hydrogen terminated Si(100) surfaces was performed in a silicon molecular beam epitaxy system, using reflection electron energy loss spectroscopy, in conjunction with conventional reflection high energy ...

Enantiospecific mirror-imaged growth in overlayers of enantiopure thiadiazole-[9]helicene on Au(111) without commensurability

Applied Physics Express
Two-dimensional (2D) crystallization of chiral molecules on achiral crystal surfaces typically exhibits mirror-imaged growth, defined by the substrate’s mirror plane and the lattices of each enantiomer.

Coverage-dependent adsorption sites in the K/Ru(0001) system: a low-energy electron-diffraction analysis [PDF]

, 1992
The two ordered phases p(2 × 2) at a coverage θ = 0.25 and (√3 × √3)R30° at θ = 0.33 of potassium adsorbed on Ru(0001) were analyzed by use of low-energy electron-diffraction (LEED).

Non-equilibrium lattice dynamics of one-dimensional In chains on Si(111) upon ultrafast optical excitation

Structural Dynamics, 2018
The photoinduced structural dynamics of the atomic wire system on the Si(111)-In surface has been studied by ultrafast electron diffraction in reflection geometry.

Unoccupied Band Structure of NbSe2 by Very-Low-Energy Electron Diffraction: Experiment and Theory

, 2002
A combined experimental and theoretical study of very-low-energy electron diffraction at the (0001) surface of 2H-NbSe2 is presented. Electron transmission spectra have been measured for energies up to 50 eV above the Fermi level with k|| varying along ...

Preparation and photoemission investigation of bulk-like a-Mn films on W(110) [PDF]

, 2009
We report the successful stabilization of a thick bulk-like, distorted $\alpha$-Mn film with (110) orientation on a W(110) substrate. The observed $(3\times3)$ overstructure for the Mn film with respect to the original W(110) low-energy electron ...

Interference between quantum paths in coherent Kapitza–Dirac effect

New Journal of Physics, 2019
In the Kapitza–Dirac effect, atoms, molecules, or swift electrons are diffracted off a standing wave grating of the light intensity created by two counter-propagating laser fields.
