Electronic-Transport Properties of Al-Cu-Fe Thin Films

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 comparison between different annealing states of the amorphous and the resulting quasicrystalline phase done on the same sample shows aston-ishing parallels in conductivity and large differences in thermopower.

Fabrication of High Quality QC Films via the Route of the Amorphous Phase

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. A direct transition from the a- to the i-phase occurs for Al-Cu-Fe films at 430 C on the time scale of minutes. The resulting films are of good quality as shown by diffraction and electronic transport properties. The surface of the resulting films is very smooth.
