ベルト型高圧装置による窒化物単結晶合成と不純物制御による機能発現

Synthesis of cubic boron nitride (cBN) and aluminum nitride (AlN) single crystals and rare-earth (RE) element doping were carried out by using a belt-type high-pressure (HP) apparatus. Typical emission spectra originated by doped RE, such as Ce and Eu, were observed. Ab-initio theoretical study and transmission electron spectroscopy analyses were carried out to elucidate a capability of cBN and AlN system with large size mismatch dopant system.
