Quasicrystals (QCs) may show all types of disorder phenomena observable in periodic crystals (e.g., substitutional or displacive disorder). Other types of disorder are special for QCs (e.g., phasonic disorder) or are better understood in higher dimensional description (e.g., out-of-phase domains, disordered superstructures). Contrary to periodic crystals, observation of diffuse scattering in diffraction experiments is not necessarily a proof for the presence of disorder. Even in cases of perfectly ordered QCs, limited experimental resolution leads ...
