Abstract:
1. A method of growing a plurality of free-standing structures comprising: providing a plurality of free-standing structures, each free-standing structure having a first end coupled to a substrate, and a terminal end; providing at least one laser beam, the laser beam having a beam waist at a point proximate to the terminal end of the free-standing structure; moving one of the plurality of free-standing structures or the beam waist to provide a growth zone proximate to the terminal end of each of the free-standing structures such that the free-standing structures grow into the growth zones by addition of decomposing precursor gas components; maintaining growth rates of each of the free-standing structures substantially the same in-parallel in a state of mass-transport limitation by limiting the amount of precursor gas components supplied to the growth zone to rate-limit growth of the free-standing structures.
