IRG 2: Breaking the Mold to Produce Submicron Polymeric Gratings with Large Areas :: Princeton University
[ Research]
Princeton scientists have developed a new method for making gratings by prying apart two rigid plates that sandwich a thin, glassy polymeric film. The process fractures the film into complementary sets of ridges on each plate, with highly uniform ridge spacings ranging from 200 nm to 200 µm, scaling directly with the film thickness.
