摘要：
Electron-microscopy images of 〈001〉-GeNb9O25 obtained at the atomic resolution have been studied at the electron energy E = 80 keV. It is established that one of the sublattices on the image is displaced with respect to the other sublattices. The nature of this displacement is interpreted in terms of physics. The effect was studied in the formalism of Bloch waves. The important role of the valence Bloch state is also considered.
