Nanoscale Dots, Grids, Ripples, and Hierarchical Structures on PET by UV Laser Processing

Nanoscale Dots, Grids, Ripples, and Hierarchical Structures on PET by UV Laser Processing

Nanostructures can be produced on poly(ethylene terephthalate) (PET) foils by using a krypton fluoride (KrF) excimer laser with a wavelength of 248 nm and a pulse duration of about 20 ns. We show that surface nanoripples, nanodots, nanogrids, and hybrid patterns of ripples with dots or finer ripples...
