Layering rough surfaces with nanometer-thin optical interference coatings opens new array of possible applications

Tuesday, September 30, 2014 - 10:00 in Physics & Chemistry

Applying a well-known optical phenomenon called thin-film interference, a group of researchers at Harvard University has demonstrated the ability to "paint" ultra-thin coatings onto a rough surface—work that holds promise for making future, flexible electronic devices, creating advanced solar cells and detailing the sides of next-gen rocket ships and spacecraft with extremely lightweight decorative logos.
