Abstract
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.
