Hi,
You could build a 3D box with an unusually large size in one direction
(say z), that would approximate a 2D situation. I think you want to model
a surface and study some surface properties. THis approximation should be
fine for you.
You also had a question about what force field to use to model
hybrid organic-inorganic interactions (you said something about Al). A
possibility (although limited)
would be to use the MSQ force field developed in the Goddard group at
Caltech (www.wag.caltech.edu)
The MS-Q Force Field for Clay Minerals: Application to Oil Production
S. Hwang, M. Blanco, E. Demiralp, T. Cagin, and W. A. Goddard III
J. Phys. Chem. B 105, 4122 (2001)
The MSXX Force Field for the Barium Sulfate-Water Interface
Yun Hee Jang, Xiao Yan Chang, Mario Blanco, Sungu Hwang, Yongchun
Tang, Patrick Shuler, and William A. Goddard III
J. Phys. Chem. B, 106, 9951 (2002)
Just a short notice: the MS-Q force field was developed to work in tandem
with the charge equilibration method.
