| Research Abstract |
In this study, epitaxial thin film of various hexaboride series including LaB6, BaB6, SrB6, CaB6,(La, Sr) B6, and(Sr, Ca) B6 s were fabricated successfully by means of laser molecular beam epitaxy(laser MBE). These epitaxial boride thin films are expected wide applications such as thermoelectric conversion materials, a high current density field emission flat source, and high-temperature electronic devices. Through the various film processing such as substrate-surface engineering were applied for development of film epitaxy, we could obtain the knowledge on the new material science concerning with the crystal growth of boron-octahedron cluster structure.
