摘要：

Transmission electron diffraction and imaging were applied to derive a proposal for the tilt scheme of the perovskite-based structure of silver niobate (AgNbO3). Electron diffraction data enable a reduction of the possible space groups down to two, each compatible with a number of tilt schemes for the octahedra in the perovskite-like structure. With the aid of high-resolution imaging a single tilt scheme can be proposed. The HREM image interpretation is substantiated by image simulation based on the real space patching method.
