Abstract

Structural analysis of the fivefold i-Al-Cu-Fe surface based on new scanning tunneling microscopy (STM) results and a recent refined structure model of the isostructural i-Al-Pd-Mn was investigated. It was found that the surface corresponds to the bulk truncations at the positions where blocks of atomic layers were separated by larger interlayer spacings. STM images were recorded at room temperature with an Omicron STM with tunneling currents of 0.15-0.25 nA and bias voltages of 1.0-2.6 V. Both step-height distribution and high resolution images on terraces strongly reveal that the surface corresponds to the bulk truncations at larger interlayer spacings.
