![]() of a tiny model of a ZnO nanowire. "LUMO" means lowest unoccupied molecular orbital; this orbital is one of a doublet lying just below the singly degenerate HOMO ("highest unoccupied molecular orbital.) Simple ideas of molecular orbitals plus symmetry (group theory) allow you to predict things like this. (Figure from Xiao Shen cond-mat/0610002) |
