ARHVTEM of the Pd/ZnO heterointerface chemical structure.

Atomic-resolution high-voltage transmission electron microscopy was applied to the atomic structure analysis of a well-defined Pd/ZnO polar interface, which was produced by internal oxidation. Viewing the ZnO along <1120> axis, each atomic column consists of either oxygen or zinc, so that an individual column was directly identified from the image contrast of the picture taken at the Scherzer defocus condition. The terminating chemical element at the Pd/ZnO interface, which is parallel to [111]Pd and to [0001]ZnO, was shown to be zinc but not oxygen on both sides of the precipitate.

Atomic structure observation of silicon carbide using HRTEM.

Atomic-resolution high-resolution high-voltage transmission electron microscopy was applied to the chemical structure analysis of silicon carbide. Each atomic column was imaged in dark contrast. Silicon and carbon were distinguished from each other in image contrast, i.e. silicon appeared in darker contrast and carbon appeared in lighter contrast. For the projected potential image to provide chemical structure information, it was estimated that the specimen thickness needs to be less than 5 nm. The precise atomic columnar site was determined by using the maximum entropy method.

Imaging of a single atomic column in silicon grain boundary.

Atomic resolution high voltage electron microscopy was applied in investigations of the atomic structure of [112] sigma3 CSL grain boundary of silicon. Images of the grain boundary, viewed in the < 110 > direction, showed two types of dark spots. One type was rod shaped, which represented an atomic pair aligned in the < 111 > direction. The other was a small round spot, which represented a single atomic column in the grain boundary. The atomic structure of [112] sigma3 CSL grain boundary was directly shown from the atomic-structure image.
