Description
Using low-energy electron diffraction and scanning tunneling microscopy, we found that epitaxial NaCl films grown on Ge(100) with thicknesses up to (at least) 15 monolayers can be modulated with a period of six lattice constants and an amplitude directed mainly normal to their surface. The (6x1) periodicity on the NaCl films is induced by a preadsorbed Na layer at very low coverages (Θ≅0.06), that form chain structures with a sixfold periodicity in one dimension. At 10 monolayers thickness of NaCl a modulation amplitude of 0.28 Aa was obtained
