Abstract:
1. A method comprising: forming a substantially close packed dense layer by assembling a plurality of anisotropic nanoparticles wherein the plurality of nanoparticles includes a member selected from the group consisting of (In,Ga) imposing a delocalized force that defines a direction that is substantially perpendicular to a basal plane of the substantially close packed dense layer; and imposing a fluctuating force to which the anisotropic nanoparticles respond, wherein fluctuations in a magnitude of the imposed force are sufficient to overcome a short range weak attractive force between members of the plurality of anisotropic nanoparticles with respect to anisotropic nanoparticles that are not substantially overlapping, and wherein assembling further includes arranging the plurality of anisotropic nanoparticles to define an order having one-dimensional translational periodicity and a rotational symmetry selected from the group consisting of eight fold, ten fold and twelve fold with respect to a normal to the basal plane of the substantially close packed dense layer, and wherein the plurality of anisotropic nanoparticles are substantially aligned with respect to each other to define the substantially close packed dense layer and the substantially close packed dense layer has a non-random shared crystallographic orientation that is substantially aligned with the basal plane of the substantially close packed dense layer.
