Beschreibung:
  • We report on a STM study of clean W(110) and the so-called R(15 × 3) and R(15 × 12) carbon-induced reconstructions of the W(110) surface on the atomic scale. The dimensions of the unit cells of both reconstructions, until now only known from diffraction experiments, are confirmed. Depending on the tunnelling gap resistance the inner structure of the R(15 × 3) unit cell is resolved. The experimental results provide strong evidence, that this structure is formed by a periodic surface lattice deformation. © 1995.
