 Equilibrium nanostructured 1D surface of a growing crystal subject to  interference pulsed  heating. Distance between interference fringes decreases  from (a) to (f).

 Figure to the right shows coarsening kinetics for the isothermal situation (lower  data set) and two non-isothermal cases characterized by different separation    distances between fringes.		 result2_pattern.jpg
