Abstract:
1. A method of fabricating a semiconductor structure, the method comprising: forming an anisotropic nanocrystalline core from a first semiconductor material, the anisotropic nanocrystalline core having an aspect ratio between, but not including, 1.0 and 2.0; and forming a nanocrystalline shell from a second, different, semiconductor material to completely surround the anisotropic nanocrystalline core, wherein the nanocrystalline shell has a center, wherein the nanocrystalline shell extends in a first direction along a first axis and extends in a second direction along a second axis perpendicular to the first axis, and wherein the anisotropic nanocrystalline core is formed off-center with respect to the nanocrystalline shell in the first direction along the first axis and off-center with respect to the nanocrystalline shell in the second direction along the second axis, and wherein the nanocrystalline shell is longer in the first direction than in the second direction.
