Data on the annealing of NbTiVZr at 1200 °C with slow cooling rate

Data in Brief, 2019
The data presented here is complementary to the publication entitled “High temperature, low neutron cross-section high-entropy alloys in the Nb-Ti-V-Zr system” [1]. A homogenization methodology with slower cooling rate (∼2 °C/min) was performed.

DESORPTION OF Te CAPPING LAYER FROM ZnTe (100): AUGER SPECTROSCOPY, LOW-ENERGY ELECTRON DIFFRACTION AND SCANNING TUNNELING MICROSCOPY

Journal of Fundamental and Applied Sciences, 2016
The influence of the annealing temperature to desorb a protective Te capping layer of the zinc telluride (ZnTe (100)) surface was investigated. The surface reconstruction of the ZnTe (100) upon the removal of a Te capping layer grown by the molecular ...

Molecular beam epitaxy of TmTe thin films on SrF2 (111)

AIP Advances, 2022
The odd parity nature of 4f states characterized by strong spin–orbit coupling and electronic correlations has led to a search for novel topological phases among rare earth compounds, such as Kondo systems, heavy Fermions, and homogeneous mixed-valent ...

X-ray in-line holography and holotomography at the NanoMAX beamline

Journal of Synchrotron Radiation, 2022
Coherent X-ray imaging techniques, such as in-line holography, exploit the high brilliance provided by diffraction-limited storage rings to perform imaging sensitive to the electron density through contrast due to the phase shift, rather than ...

Investigation of CuGaSe2/CuInSe2 double heterojunction interfaces grown by molecular beam epitaxy

AIP Advances, 2015
In-situ reflection high-energy electron diffraction (RHEED) observation and X-ray diffraction measurements were performed on heterojunction interfaces of CuGaSe2/CnInSe2/CuGaSe2 grown on GaAs (001) using migration-enhanced epitaxy.

The Concentration of C(sp³) Atoms and Properties of an Activated Carbon with over 3000 m²/g BET Surface Area

Nanomaterials, 2021
The alkaline activation of a carbonized graphene oxide/dextrin mixture yielded a carbon-based nanoscale material (AC-TR) with a unique highly porous structure. The BET-estimated specific surface area of the material is 3167 m2/g, which is higher than the

Coherent Electron Source for Ultrafast Electron Diffraction and Imaging

EPJ Web of Conferences, 2013
We numerically investigate the suitability of photoexcited nanotips as a source of coherent femtosecond single electron pulses for ultrafast surface-sensitive electron diffraction and non-destructive imaging with low-energy electrons.

Electronic and Geometric Corrugation of Periodically Rippled, Self-nanostructured Graphene Epitaxially Grown on Ru(0001)

, 2010
Graphene epitaxially grown on Ru(0001) displays a remarkably ordered pattern of hills and valleys in Scanning Tunneling Microscopy (STM) images. To which extent the observed "ripples" are structural or electronic in origin have been much disputed ...
