Abstract:
1. A method for fabricating a three dimensional nanowire lattice, comprising: providing a thin single crystal film in a growth chamber; providing in the growth chamber a bulk single crystal substrate of the same material as the film; creating a force that induces an array of periodic non-uniform elastic fields on the surface of the film; introducing a seed alloy material in a gaseous form into the growth chamber until a plurality of nanocrystals nucleate on the film at a plurality of locations determined by the array of periodic non-uniform elastic fields; removing the force associated with inducing the array; and after removing the force, introducing a second material in a gaseous form into the growth chamber under a vapor-liquid-solid (VLS) growth condition suitable to inducing epitaxial growth of a nanowire of the second material.
