Sweeping Lasers Snap Together Nanoscale Geometric Grids

New technique developed by Brookhaven Lab scientists rapidly creates multi-layered, self-assembled grids with fully customizable shapes and compositions

(June 23, 2015)  Down at the nanoscale, where objects span just billionths of a meter, the size and shape of a material can often have surprising and powerful electronic and optical effects. Building larger materials that retain subtle nanoscale features is an ongoing challenge that shapes countless emerging technologies.

Now, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a new technique to rapidly create nano-structured grids for functional materials with unprecedented versatility.

"We can fabricate multi-layer grids composed of different materials in virtually any geometric configuration," said study coauthor and Brookhaven Lab scientist Kevin Yager. "By quickly and independently controlling the nanoscale structure and the composition, we can tailor the performance of these materials. Crucially, the process can be easily adapted for large-scale applications."
