Abstract: Deterministic organization of nanostructures into micro-scale geometries is essential for the development of materials with novel mechanical, optical, and surface properties. We demonstrate scalable fabrication of 3D corrugated carbon nanotube (CNT) microstructures, via an iterative sequence of vertically aligned CNT growth and capillary self-assembly. Vertical micro-bellows and tilted micro-cantilevers are created over large areas, and these structures can have thin walls with aspect ratios exceeding 100:1. We show these structures can be used as out of plane microsprings with compliance determined by the wall thickness and number of folds.
