Covalent bonding in NiO: Evidence from a combined STM, LSDA plus U and EELS study
We show STM images that display fourfold symmetry hole states around point defects on the NiO (001) surface that are a number of times larger than the unit cell. The observation of these spatially delocalised states demonstrates that a reasonable description of bonding in NiO must go beyond a simple...
