Abstract

The structure of the Al-Rh-Cu decagonal quasicrystal with periodicity of about 0.4nm has been investigated by high-resolution electron microscopy. A high-resolution structure image taken with the incident electron beam parallel to the tenfold axis can be interpreted as an aperiodic tiling composed of three kinds of subunit. The atomic arrangements in these subunits have been proposed according to the structure of the Al-Co-Cu decagonal quasicrystal determined by single-crystal X-ray analysis. A calculated image using the present model reproduces well the contrast features of the high-resolution structure image.
