cover: Dynamic stencil lithography is an emerging technique for fabricating arbitrary two-dimensional nanostructures. In this colorized scanning electron micrograph, the stencil (orange) is a dodecagonal plate 155 μm across; it moves over a substrate while atoms rain down from above. Each of the squares in the middle of the stencil contains a 200-nm aperture, not visible in the image. The shutter (purple), positioned above the stencil, stops and starts the flow of atoms through the apertures. For more on dynamic stencil lithography and other nanomanufacturing methods, turn to the article by Matthias Imboden and David Bishop on page 45.
