The tungsten surface covered with half a monolayer of oxygen reconstructs upon annealing. In this process a domain structure was generated. The average domain size was found to be a function of annealing temperature and time. An attempt was made to explain the experimentally observed growth rates during isothermal anneals by a simple model based on place exchange and diffusion with an activation energy of 1.88eV.
