Phonons, phasons, and dislocations in quasicrystals
The detailed relationship between the density-wave and unit-cell descriptions of quasicrystals is examined. It is shown that phonons, phasons, and dislocations correspond to translations, distortions, and rearrangements of unit cells. The associated density-wave images closely resemble experimental...

| description | The detailed relationship between the density-wave and unit-cell descriptions of quasicrystals is examined. It is shown that phonons, phasons, and dislocations correspond to translations, distortions, and rearrangements of unit cells. The associated density-wave images closely resemble experimental electron micrographs of the icosahedral phase of Al--Mn and related alloys. Partial dislocations are also discussed and a natural classification scheme for partials is proposed. 30 ref.--AA(US). |
