SHAPES OF QUASI-CRYSTALS

In the present article, we review the present status of our understand ing of the shapes of quasicrystals. Although theoretical efforts exist to determine the equilibrium shape of quasicrystals, very little expe rimental information exists. We report some preliminary results of our work in this direction. On the other hand, beautiful growth shapes of quasicrystals are reported in the literature. However, only recently theoretical attention is paid to the. problem of atomistic mechanism o f growth, In spite of limited studies, comparison of theory and experi ments reveal a difference in growth behaviour between crystal and quas icrystal.
