Icosahedral quasicrystals by optical interference holography
نویسنده
چکیده
Optical interference holography has been proven to be a useful technique in fabricating periodic photonic crystals in which electromagnetic waves are forbidden in certain frequency band gaps. Compared to periodic crystals, quasicrystals, having higher point group symmetry, are more favorable in achieving complete band gaps. In this letter, we propose two seven-beam optical interference configurations based on the reciprocal vector space representation to fabricate icosahedral quasicrystals. Interference simulations for the quasicrystals exhibit the full symmetry of an icosahedron. The result paves the way for the fabrication of photonic quasicrystals using holographic lithography. © 2006 American Institute of Physics. DOI: 10.1063/1.2408651

Continuum elastic sphere vibrations as a model for low-lying optical modes in icosahedral quasicrystals
The nearly dispersionless, so-called “optical” vibrational modes observed by inelastic neutron scattering from icosahedral Al-Pd-Mn and Zn-Mg-Y quasicrystals are found to correspond well to modes of a continuum elastic sphere that has the same diameter as the corresponding icosahedral basic units of the quasicrystal. When the sphere is considered as free, most of the experimentally found modes ...
متن کاملAnisotropic optical conductivity of decagonal quasicrystals.
The optical conductivity of high quality decagonal quasicrystals of Ales Co&qCu&s and A162Co~5CupoSi3 shows a strong anisotropy between the periodic and the quasiperiodic directions. We suggest that this is due to the dramatic enhancement of scattering in the quasiperiodic planes. The analysis of the conductivity reveals a drastic difFerence between the electronic structure of the decagonal qua...
متن کاملNon-linear generalized elasticity of icosahedral quasicrystals
Quasicrystals can carry, in addition to the classical phonon displacement field, a phason displacement field, which requires a generalized theory of elasticity. In this paper, the third-order strain invariants (including phason strain) of icosahedral quasicrystals are determined. They are connected with 20 independent third-order elastic constants. By means of non-linear elasticity, phason stra...
متن کاملAtom Clusters with Icosahedral Symmetry in Cubic Alloy Phases Related to Icosahedral Quasicrystals
Icosahedral symmetry can not be allowed to exist in crystalline phases. However, the structures of some crystalline alloy phases are characterized by packing of atom clusters with icosahedral symmetry, and their structures are considered to be closely related to the structures of icosahedral quasicrystals. For examples, a cubic α-(AlMnSi) crystalline phase with a lattice constant of 1.264 nm is...
