Self-Assembly of Particles for Densest Packing by Mechanical Vibration
PHYSICAL REVIEW LETTERS. week ending 31, DECEMBER 2006, PRL 97, 265501 (2006)，-0001，（）：
It is shown that by properly controlling vibrational and charging conditions, the transition from disordered to ordered, densest packing of particles can be obtained consistently. The method applies to both spherical and nonspherical particles. For spheres, face centered cubic packing with different orientations can be achieved by monitoring the vibration amplitude and frequency, and the structure of the bottom layer, in particular. The resultant force structures are ordered but do not necessarily correspond to the packing structures fully. The implications of the findings are also discussed.
