Each bubble’s curvature encodes properties such as sheet flexibility and adhesion. Stacking atomically thin materials opens a pathway toward new energy and electronic applications.
“We discovered a new method to measure adhesion of layered materials at very small length scales,” said Petro Maksymovych. “It’s a simple way to probe a large number of two-dimensional materials and ask how their mechanical properties vary with modifications. It also opens an avenue for atomic-scale control over 2D materials without defects, which may prove useful to achieve their full potential in future technologies.”
