Document Summary
Engineering 1a lecture 17: band structures in extended solids. Band structures in extended solids: band structure diagram , band diagrams are defined by the energy levels of the constituent diagram. Band diagrams are analogous to molecular orbital diagrams. A very general expression for an infinite chain a. If there are n atoms in the chain, there will be n energy levels and n electronic states or extended molecular orbitals. n. When you bring two sodium atoms together, the. 3s energy level splits into two separate energy levels. You could minimize electron energy by putting both 3s electrons in the lower energy level, one spin up and the other spin down. There is an internuclear separation which minimizes electron energy. If you bring the nuclei closer together, energy increases. When you bring five sodium toms together, the 3s energy level splits into five separate energy levels.
