ALN CRYSTAL PREPARATION METHOD, ALN CRYSTALS, AND ORGANIC COMPOUND INCLUDING ALN CRYSTALS

摘要

An AlN crystal preparation method includes using at least one element excluding Si that fulfills the condition that a compound is not formed with either Al or N or the condition that a compound is formed with either Al or N but the standard free energy of formation of said compound is greater than the standard free energy of formation of AlN. In the preparation method, a composition including at least Al and the element is melted. Al vapor and nitrogen gas are reacted at a prescribed reaction temperature. AlN crystals are formed.
