Abstract
A method for selectively controlling lengths of nanowires in a substantially non-uniform array of nanowires includes establishing at least two different catalyzing nanoparticles on a substrate. A nanowire from each of the at least two different catalyzing nanoparticles is substantially simultaneously grown. At least one of the nanowires has a length different from that of at least another of the nanowires.
Claims25
A method for selectively controlling lengths of nanowires in a substantially non-uniform array of nanowires, the method comprising:
- establishing at least two different catalyzing nanoparticles on a substrate;
- and
- substantially simultaneously growing a nanowire from each of the at least two different catalyzing nanoparticles, wherein at least one of the nanowires has a length different from that of at least an other of the nanowires.
A method for forming a substantially non-uniform array of nanowires, the method comprising:
- establishing a plurality of catalyzing nanoparticles on a substrate, at least two of the plurality of catalyzing nanoparticles being different from each other;
- and
- substantially simultaneously growing a nanowire from each of the plurality of catalyzing nanoparticles, wherein the nanowire grown from one of the at least two different catalyzing nanoparticles has at least one of length and diameter different from that of the nanowire grown from an other of the at least two different catalyzing nanoparticles.
A method for forming an array of nanowires, the method comprising:
- establishing at least two catalyzing nanoparticles on a substrate in a predetermined pattern, a portion of the substrate remaining exposed;
- substantially simultaneously growing at least one nanowire from each of the at least two catalyzing nanoparticles;
- establishing at least two layers on the exposed portion of the substrate;
- and
- selectively removing one of the at least two layers such that a channel is formed, the channel having the array of nanowires extending therethrough.
