Nanoscale Self-Organization Using Standing Surface Acoustic Waves

Saturday, January 15, 2011

Who has never observed the self-organisation of a bunch of sand on a vibrating plate to form geometric figures ? The computational physicists of the “Crystalline Materials under Stress” group in Cemes have transposed this principle at the nanoscale. During an atomic deposition process, the adatoms diffusing on a substrate submitted to a surface standing acoustic wave are preferentially located in the vicinity of the wave displacement maxima.
