| Research Abstract |
In this study, we utilized the effects caused by the interaction between plasma and nano-interface of materials. We pursued this subject from the stand point of view of materials science. The structural analyses of obtained materials by using x-ray diffraction played an important role, and which led to discoveries of new polytypes of sp3- bonded BN. In order to understand their nature in terms of inorganic chemistry, we newly introduced Komatsu diagram, in which crystallographic indices such as hexagonality, close-packing index, metastable energy, and iconicity are found to be related systematically. As to the growth mechanism of the metastable polytypic forms, we found a consistent relationship between the B-N bond lengths and preferably grown structures. This led us to find the Bond-Strength Initiative Rule in the CVD growth of metastable structures.
