Physicists turn a Crystal into an Electrical Circuit

Washington State University researchers used light to write a highly conducting electric path in a crystal. This opens up the possibility of transparent, three-dimensional electronics that, like an Etch-A-Sketch, can be erased and reconfigured.

Transparent, 3D electronics can be configured and erased like an Etch A Sketch. It serves as a proof of concept for a phenomenon that WSU researchers first discovered by accident 4 years ago. At the time, a doctoral student found a 400-fold increase in the electrical conductivity of a crystal simply by leaving it exposed to light...
