How Do Icosahedral Quasi-Crystals Differ from Polygonal Quasicrystals?

[peterjaybee]

Hello,

Please could someone explain what properties an icosahedral quasi crystal has which make it differ from a polygonal quasicrystal. (I assume it has something to do with rotational symmetry)

Regards,
Peter

reffer to the book "atomic and electronic structure of solids" by efthimios kaxiras

there you can find a brief but useful description of icosahedral crystals..

hope it helps
