(Phys.org)—Technologies such as microelectronics and lithography require nanoscale polymer films that sit atop various other materials. An understanding of the interplay between the dynamics of the thin film and the underlying substrate is crucial in determining the appropriate materials to be utilized for new and improved applications. Recent experiments at the U.S. Department of Energy Office of Science's Advanced Photon Source (APS) at Argonne National Laboratory provide new insights on the dynamics of thin polymer films sitting on various substrates and the importance of film thickness and supporting material properties on the surface dynamics of thin polymer films.
