| Abstract: | The Epitaxy of single silver crystals on tungsten single crystal surfaces in UHV is studied. The substrate was a W-ribbon recrystalized at high temperature. After the high temperatur treatment many differently oriented single crystal regions appeared on substrate surface. The orientation of the single crystal regions crystal regions was determined by means of etch pits. The experimentally found change of the silver crystal orientation with changing the substrate orientation gives the following epitaxial relationship  It is shown that the observed epitaxial growth of silver on tungsten is due to the structural similarity of the parallel growing Ag/W-planes. |
