ABSTRACT

The structure and chemistry of heterophase boundaries, such as metal/metal oxide interfaces, can be resolved by dedicated techniques of transmission electron microscopy. High-resolution transmission electron microscopy (HREM) reveals the structure with high precision. The coordinates of atom columns can be detected with an accuracy of ±O.02 nm. However, only the projected structure of the interface can be revealed if (i) both crystals (adjacent to the interface) are oriented parallel to low-indexed Laue zones and (ii) the interface itself is also parallel to the incoming electron beam. Analytical electron microscopy (AEM) reveals the chemical composition of the interfaces with a spatial resolution of
