摘要：

We have imaged for the first time the atomic structure of a quasicrystal using a scanning tunneling microscope. The structure of the decagonal Al65Co20Cu15 quasicrystal is described by a pentagon-center-decorated pentagonal quasilattice giving strong evidence for a tiling model. The scanning-tunneling-microscope measurements of the surface are in good agreement with the high-resolution x-ray-diffraction measurements of the bulk. © 1990 The American Physical Society.
