Using new computer technology based on gaming machines, scientists were able to use a combination of molecular dynamics and quantum mechanics calculations to simulate the electron microscopy of gold particles. By modelling the atomic vibration of individual atoms in such clusters realistically, external atoms on the surface of the structure can be 'seen' to vibrate more than internal atoms. The research is published in the latest issue of Physical Review Letters.
Currently, electron microscopy only allows scientists to estimate the average position of atoms in a three-dimensional structure. This new technique means that, for the first time, the difference in individual atomic motion can also be considered, enabling more accurate measurements of an atom's position and vibration in small particle structures.
This new development paves the way for a new field of dynamical study in the position dependence of atomic vibration in small particles, and is also likely to benefit the catalytical study of particles.
