Abstract
It is demonstrated that the moiré fringes of the incommensurate quasihexagonal reconstructed overlayer and the underlying Au(001) substrate can be used as a "magnifier" to study subsurface imperfections with scanning tunneling microscopy, and that an unprecedented lateral precision of better than 0.1 Å can be achieved in the measurement of atomic shifts by means of scanning tunneling microscopy. As moiré fringes exist in many surfaces and adsorbate systems the method is expected to have wide applications.
