Ammonothermal Crystal Growth of Indium Nitride [PDF]

, 2022
S.2365-2369InN crystals with hexagonal shapes were grown from InCl3 and KNH2 in supercritical ammonia at around 280 MPa. For a successful crystal growth a molar ratio of the chloride to the amide of 1:3 was applied, thus providing an essentially ...
