Magnetoconductivity of icosahedral and amorphous Al-Pd-Re films - a comparison
R. Haberkern, R. Rosenbaum, H. Bekar +4
The magnetoconductivity of quasicrystals is often discussed in the frame of quantum corrections, namely weak (anti-) localiza-tion and electron-electron interaction. A premise for…
Electronic Transport Properties of Quasicrystalline Thin Films
Roland Haberkern
Quasicrystals are assumed to be electronically stabilized by a Hume-Rothery type mechanism. This explains most of the peculiar properties of quasicrystals. The stabilization is inv…
Fabrication of High Quality QC Films via the Route of the Amorphous Phase
R. Haberkern, C. Roth, R. Knoefler +2
We discuss the preparation of thin icosahedral films (Al-Cu-Fe and Al-Pd-Re) via the route of the amorphous (a-)phase which in some aspects is a precursor to the icosahedral phase.…
Electronic-Transport Properties of Al-Cu-Fe Thin Films
R. Haberkern, C. Roth, R. Knoefler +2
Amorphous samples of Al-Cu-Fe were crystallized to the icosahedral phase under the control of electrical conductivity and thermopower at a rather small temperature of T=720 K. A co…
