Thanks for that. That helped quite a bit - of course I should have checked wiki first at the very least. Silly me.

Cheers. When you say small, what is the order of difference? In the case of a, say, disordered FCC structure how many vacancies would be needed before the structure loses symmetry and say, no longer shows FCC-type diffraction peaks?

Hey, I'm not 100% sure but sounds as if looking into diffraction peak-broadening and peak-shift effects might be your thing. Not sure if its entirely applicable but: http://www.jmst.org/fileup/PDF/02459.pdf and of course.. Warren's book on x-ray diffraction...

Hi all, Without first delving too deeply into the literature I wanted to ask if its is only permissible for FCC structures to have a coordination number of 12. In the case of lattice vacancies and/or distortion: wherein the atomic sites are slightly displaced; is there a kind of tolerence for...

I've been introduced to ligand-field theory lately and was then wondering what roles f orbitals play in the magnetic properties of elements and alloys. Apparently f orbitals behave oddly in that they hybridize in weird ways because they're so large and that the crystal field actually affects the...

Oh apologies for reviving an old thread, but I thought if anyone was interested in the matter they could read this under the sub-section of interatomic potentials http://www.uic.edu/labs/trl/1.OnlineMaterials/nano.publications/03.Nanostructures.InterMoleForce.pdf and proceed from there onwards

Thank you :)

Ooooh thanks. I had a look at that and it looks rather useful at understanding the subject matter. However it seem to not elucidate on the potential in solids. I'm wondering if the Lenard Jones potential/interatomic potentials can describe the mechanical properties of a solid and been trying...

Dear All, Recently I've started looking at the Leonard-Jones potential for a project; and I'm trying to look for a book that covers the potential in additional detail beyond the standard +ve and -ve contributions. Can anyone please recommend some books for further reading? Most of the books...
