Abstract

We present scanning tunneling microcopy (STM) studies of three different icosahedral (i) quasi-crystals of the same family, namely, i-Al-Cu-Fe, i-Al-Pd-Mn, and i-Al-Cu-Ru. STM images reveal that the fivefold surface of all three quasi-crystals is isostructural. Both step-height distribution and high-resolution images on terraces are consistent in all systems.
