Some numerical studies of roughening made with SOS (Solid-On-Solid) models, some as interfaces in Ising models. Some by simulation some by series expansions. The SOS models were also applied to telescope phasing, not discussed further here.
- I became involved in the numerical side of roughening, during a sabbatical in Seattle,
where I took over supervising a friend's project student, E. Arian.
- On my return, Steve Lipson suggested continuing this direction, to connect with his experimental work.
3 students, Gidi Baum, Sasha Gemintern and then Adham Hashibon worked with us.
- Simulations along the facets requires attention to boundary conditions and equilibration.
- Thruout these projects we searched for ways to visualize the crystal surfaces. The first is shown at left, TOPDRAW in Seattle.
- The rest will be covered in the following slides.
