Fabrication of two-dimensional metallodielectric quasicrystals by single-beam holography

Abstract

We experimentally demonstrate a single-beam holography for creating Ag nanoparticle-embedded eight-fold quasicrystals. By adjusting the phase relation of interference beams through an optical mask, we obtain eight-fold symmetry structures with three different profiles. The structure of quasicrystals is confirmed through scanning electron microscopy and optical diffraction pattern, respectively, Furthermore, we also numerically demonstrate that the method can encode even higher symmetric structures such as the most complex 14- and 18-fold quasicrystals as well by computer simulations. © 2006 American Institute of Physics.
