Profile of a Faceted Macrostep Caused by Anomalous Surface Tension

Figure 3

Faceting diagram of the p-RSOS model for a vicinal surface obtained by the DMRG method. Squares: calculated . For , the surface tension is discontinuous (disconnected, more precisely) around the (111) surface. Triangles: calculated . For , the surface tension is discontinuous around the (001) surface. Open circles: calculated roughening transition temperatures of the (001) surface. Solid line: zone boundary line calculated by the two-dimensional Ising model. For the definition and details about QI Bose solid, QI Bose liquid, and QI Bose gas, refer to [5]. This figure is taken from [5].
