Long- and Short-Range Order Fluctuations in the H/W(100) System

  • Roy F. Willis
Part of the Springer Series in Surface Sciences book series (SSSUR, volume 2)


The surface reconstruction phase transformations of W(100) can be understood in terms of periodic lattice distortion instabilities. A mechanism of non-linearly coupled phonon soft modes produces a system of antiphase domain walls which can be viewed as a “soliton superlattice”. Many aspects of the behavior of W(100) with variation in temperature and hydrogen coverage can be understood in terms of long- and short-range order fluctuations of this lattice dynamical model.
