Solid-state physics: How does your quasicrystal grow?

Paul J. Steinhardt1

Top

Somewhere between the amorphous glasses and the rigidly regimented periodic crystals lie the quasicrystals: ordered, predictable, yet non-periodic arrangements of atoms. How do these strange structures form?

Just as it's easy to construct a mosaic of square tiles simply by adding tiles one at a time, so it's little trouble for atoms to arrange themselves into an analogous, perfectly periodic pattern: a crystal. The rules for constructing another class of mosaic — a quasicrystal — seem to be much more complex.
