However the study of metal - oxide hetero - interface is relatively less because the properties of metals and oxides usually differ extremely from each other. contrary to metals, the oxides are usually very brittle, elastically stiffer, insulating and exhibit less thermal expansion and their crystal lattice constants are different from metals. moreover, the preparation of specimen of metal - oxide interface is very difficult, the observation of searching a suitable interface under the electron microscope is also a tedious work
