LITHOGRAPHY USING NANO-LENS ARRAYS MADE OF LIGHT

We discuss the fabrication of various one and two-dimensional chromium nanostructures. A chromium atomic beam effusing out of a thermal oven is first transversally laser cooled. This well-collimated beam is the n structured and focused by the optical dipole force in a periodic lig ht field. By introducing a substrate at the focus of the atomic beam w e are able to capture this pattern directly. We discuss a few applicat ions and challenges of this young lithography technique.
