On electronic properties of Al-Mn(-Si) quasicrystals

The authors present structural and resistivity studies of the melt-spun Al-Mn (10-20 at.% Mn) alloys which contain more than 50 vol.% of the quasicrystalline (QC) phase. Using a two-phase Landauer model, they estimate the electrical resistivity of the QC phase to be of the order 150-200 μΩ cm. The same magnitude of resistivity was measured in Al75Mn20Si5 which is almost entirely `mono' quasicrystal. The authors discuss the electronic structure and argue that electrical resistivity and high (meta)stability of quasicrystals can be understood within a framework of the Friedel model of virtual bound states
