Chladni figures at the nanoscale

Résumé

On a substrate submitted to a standing surface acoustic wave, an adatom diffuses and preferentially locates in the vicinity of anti-nodes of the transversal displacements of the wave. Using molecular dynamics simulations, the physical mechanism yielding this structuration is revealed: the adatom is mainly driven by the time-varying longitudinal displacement field of the wave. Besides, the intensity of the structuration as a function of the substrate temperature and of the amplitude, direction and frequency of the wave is studied.
