Useful Links

Atomic and molecular orbitals from the Sheffield site. Nice pictures and animations.

Webelements is a great periodic table with easy-to-access properties, electron configurations, group and period trends, etc.

Band structures of elements a periodic table that shows band structures of all the elements in their solid forms.

You can view and rotate cubic lattices at this site.

Data base of Fermi surfacepictures.

Applet that demonstrates the construction of the first few Brillouin zones of a 2-D square lattice. Also discusses the Fermi surface.

Solid state simulations. Drude model is nice.

Course on crystal diffraction. Nice examples of reciprocal space. (seems to be dead …?)

Pictures of different lattice types; rotatable.

Bilbao crystal server. Find space groups and reciprocal lattices.

Wien 2k developer website.

Portland State U's Crystallographic database. Get cif files for free!

MIT group photonic crystal research. Nice pictures.

Principles of Semiconductors is a good web book by Bart Van Zeghbroeck of Univ. Colorado. Google his name and you'll find the link. The Wiki wouldn't let me link to it for reasons I don't understand.

Link to java applet to see acoustic and optic phonon modes of diatomic chain.

Dispersion relations and animations of phonon modes in several different crystals. Also surface phonons.
