Capillary bending of Janus carbon nanotube micropillars

摘要

We present a scalable process for the fabrication of slanted carbon nanotube micropillar arrays by inclined metal deposition and capillary self-assembly. Local control of the micropillar angle from vertical to nearly horizontal is achieved, and is explained using a finite element model. These structures may be useful for micro-scale contacts and anisotropic smart surfaces.
