Kirigami Produces Unique Nanoscale Optical Elements
Origami (making 3-D shapes by folding paper) and kirigami (which allows cutting as well as folding) are ancient arts. Nano-kirigami has taken off as a field of research in the last few years, targeting not centimeter-sized pieces of paper but micron-sized flat materials with individual features at the nanoscale. Researchers in the US and China … Read more
