Symmetry Plays a Key Role in the Erasing of Patterned Surface Features

open access: yes, 2015
We report on how the relaxation of patterns prepared on a thin film can be controlled by manipu- lating the symmetry of the initial shape. The validity of a lubrication theory for the capillary-driven relaxation of surface profiles is verified by atomic ...
