QUASICRYSTALS: STRUCTURE AND PROPERTIES

Quasiperiodic structures can be described as physical irrational cut of structures which are periodic in higher dimensional spaces. Such a so-called quasicrystallography approach has been applied to several real quasicrystals. The Fourier components of these structures are densely distributed in the reciprocal space. This is at the origin of physical properties which may sound ackward for metallic systems. For instance, the electrical resistivity reaches very large values.
