Chemical Bonding in Solids

This lecture covers the band structure in solids, focusing on chemical bonding, core and valence atomic orbitals, and the formation of bands in molecules. It explains the impact of periodicity on Bloch functions, the LCAO method, and the creation of bands at k-points in the Brillouin Zone. The lecture also delves into the LCAO theory for monatomic chains, discussing the creation of bands, band dispersion, and the adjustment of orbital energies. Additionally, it explores the surface scattering techniques of GID and GIWAXS for in-plane lattice parameter measurements and crystal orientation analysis.
