SYSTEM AND METHOD FOR CONTROLLING NANOSTRUCTURE GROWTH

摘要

Systems and methods are provided for controllably growing nanostructures (201), such as nanotubes, on a substrate (101), thus enabling the length and/or orientation of the nanostructures to be selectively controlled. A substrate's surface is selectively patterned to include topological structures (102), such as a blocking structure protruding from the surface and/or a recess in the surface, for influencing the nanostructure growth along the surface from a catalyst (103). The topological structures can be located to control the length and/or orientation of the nanostructures differently on different areas of the substrate. The topological structures may be of a substance that chemically inhibits growth of the nanostructure.
