This structure may explain why the reconstruction can be obtained at lower temperature by deposition of a few aluminum layers, and why Al/Al 2 O 3 multilayers remain coherent, with aluminum of (111) orientation.doi:10.1557/proc-312-297Renaud, G....
The projected atomic structure of the α-Al2O3(0001)(√31×√31)R±9° reconstruction has been analyzed by means of the grazing incidence x-ray diffraction technique, which is not limited by the surface insulating character. It consists of two Al planes whose structure is close to that of...
(a) Multilayer structure (Si/SiO2/Al2O3/Al/Cu/Fe/SiO2; (b) Heating-cooling profile for in-situ measurements vs phase evolution for Al-Cu-Fe from in-situ XRD. Full size image The in-situ XRD measurements showed different phase transitions during the heating and cooling. A summary of the...
The atomic structure of the {001} surface of Ni3Al has been determined by LEED (low-energy electron diffraction) intensity analysis to correspond to simple truncation of the bulk structure with the Ni-Al mixed layer on top rather than the pure Ni layer. The first interlayer spacing is essenti...
These observations provide direct experimental evidence to support the general framework of the efficient cluster packing model for metallic glasses10,12,13,14,16. We expect that this work will pave the way for the determination of the 3D structure of a wide range of amorphous solids, which ...
In order to elucidate the atomic structure of the luminescent centers, we directly observe individual Ce dopants in w-AlN using annular dark-field scanning transmission electron microscopy. We find that Ce is incorporated as single, isolated atoms inside the w-AlN lattice occupying Al substitutional...

Atomic Structure refers to the fundamental components of matter, namely atoms, which consist of a nucleus and orbiting electrons. The nucleus, acting as the center of an atom, is positively charged and has a much greater mass than the negatively charged electrons. Atoms are electrically neutral ...

When the dimension of matter is reduced from the three dimensions to low dimensions or even single-atom scale, distinctive features can be observed, indicating broad application prospects in variety fields, such as energy storage and conversion, topological nanocomponents, and semiconductors.
