Abstract

A method and system for assembling a quasicrystalline heterostructure. A plurality of particles is provided with desirable predetermined character. The particles are suspended in a medium, and holographic optical traps are used to position the particles in a way to achieve an arrangement which provides a desired property.

Claims

1. An article of manufacture consisting essentially of an icosahedral quasicrystalline arrangement of selected particles in an icosahedral symmetry embedded in a matrix or domain of the article of manufacture wherein the icosahedral quasicrystalline arrangement includes at least one unit which is not repeated and thereby providing quasicrystalline symmetry in each of the units relative to other ones of the units of icosahedral quasicrystalline arrangement, each of the icosahedral structural units being positioned at a selected given position in the matrix and within the article of manufacture and deterministically organized by using holographic optical traps for translating each of the particles to move the selected particles to the selected given position with final three dimensional coordinates which arise from assembly being accomplished by use of the holographic optical traps established in accord with holographic control.

2.
