Hi, Can anyone recommend a Windows/PC program that can display crystal structures (with a given number of unit cells along each axis direction), rotate them in 3D, and allow the user to manipulate the structure, e.g. remove surface atoms, move atoms about, create/break bonds, etc. We want to examine how the surface of a diamond crytal might reconstruct to graphite as the terminating groups leave, and there must be a better way to do this than than handheld straw models? The Weblab viewer from MSI can do some of this, but it doesn't have all the functionality I'd like. Anyone know of a similar program written specifically for crystals?
