According to the map, the atoms in it are the vibrations of a small cluster of atoms. The sphere represents the range of movement of atoms, not the size of the atom itself 45 times or more. Researchers at York University in Birmingham and the University of Genoa collaborated on the development of new techniques to study the small particles of atomic vibrations, revealing the structure of atomic clusters, and more accurate images show that the surface is atomic vibrations deeper than internal atoms.
Using new computer technology based gaming machines, scientists can use a combination of molecular dynamics and quantum mechanical calculations to simulate the electron microscopic gold particles. By simulating a single atomic atomistic vibration of the cluster, external atoms on the surface of the structure can "see" vibrations more than internal atoms. The research results were published in the latest issue of Physical Review Letters.
At present, electron microscopes only allow Xu scientists to estimate the average position of atoms in a three-dimensional structure. This new technique means that, at the first time, the difference in the motions of the various atoms can also be considered, allowing the vibrations at the position of one atom to measure the structure of the small and medium particles more precisely. This new discovery paves the way for a dynamic study of the position dependence of small particles in atomic vibrations in the new field, and is also likely to benefit particles. Richard Aveyard.
Prof Yuan said that our work can already prove inconsistent with the existing experimental data, and we believe that the new experiment focuses on the dynamic performance. Atomic nanostructures allow us to understand atomic clusters and contribute to the study of dynamic structure.
