SIMULATION STUDIES OF THE FACETING TRANSITION IN A CUBIC ISING-MODEL

The faceting transition of a crystal surface can be effectively simula ted by a ferromagnetic Ising model on a simple-cubic lattice. In this paper, we study a planar interface in a fully three-dimensional Ising model, as well as an isolated bulk inclusion or droplet. We also demon strate a method for identifying the faceting transition and compare it with the conventional techniques. Finally, we examine the effect of a driving force on the faceting transition of a droplet and the so-call ed dynamic or kinetic roughening of a moving planar interface. These r esults are compared with the current renormalization analysis of the f aceting transition.
