Nanomanufacturing approach to rapidly optimize and fabricate quasi-random photonic nanostructures

NanoWerk.com - Tue, 08/01/2017 - 11:49
Quasi-periodic and random patterns in nature can exhibit extraordinary functions, such as iridescent color in bird wings, strong adhesion in gecko feet, and water repellency from lotus leaves. However, nature-inspired 3D nanostructures can be prohibitively expensive to make using modern nanoscale manufacturing processes. In new work, researchers a design approach integrated with scalable nanomanufacturing that can rapidly optimize and fabricate quasi-random photonic nanostructures.
