Quasicrystals and their spontaneous formation possibilities in the nature
Quasicrystals are a recently (1984) discovered family of structures producing X-ray diffraction diagrams with five-fold symmetry. This non-crystallographic symmetry can be explained by supposing that the strict periodic order is replaced here by a weaker order, called quasiperiodicity. Some of their...

Tartalmi kivonat: | Quasicrystals are a recently (1984) discovered family of structures producing X-ray diffraction diagrams with five-fold symmetry. This non-crystallographic symmetry can be explained by supposing that the strict periodic order is replaced here by a weaker order, called quasiperiodicity. Some of their properties as well as the possibility of formation in natural geological processes are discussed briefly in the paper. |
