The three-dimensional step structure at the buried Pb on Si(111) 6×6-Au interface is determined by utilizing the presence of quantum well states. We demonstrate that the spatial step positions as well as the step heights can be extracted nondestructively and with atomic layer precision by scanning tunneling microscopy and spectroscopy.
