Sputter deposition is used to make many products from the lining of potato chip bags to the coatings on advanced X-ray lenses. But, for decades, scientists and manufacturers have been unable to explain why these thin films sometimes peel, bend or get too rough. Now researchers have an answer: unexpected nanoparticles that form in the flux.
