Scientists at the University of Minnesota have recently been able to devise cheap ways of manipulating light in peculiar manners, when they have established new techniques to produce very smooth, patterned, thin nanofilms. According to Technology Review, their work could lead to significant improvements in the fields of optical imaging, as well as in the emerging field of optical computing. More efficient solar cells could also become available, the researchers believe. The main achievement that took place at the UM was the fact that the scientists were able to create metal films that were incredibly smooth. This is an absolute requirement when working with plasmons, which are surface waves of light that can do what regular light cannot. Plasmons can only be produced and controlled by shining light on specially patterned nanofilms, which have to be extra-smooth in order to guide the waves. Otherwise, they scatter, and the researchers cannot use films to manipulate them an!
ymore. “People have shown useful effects with plasmons, but the problem is doing it on a substrate you could cheaply and reproducibly make,†UM chemistry professor David Norris explains. He adds that, until now, experts have used high-energy ions or electrons to carve out various types of patterns with...
