Ammonothermal crystal growth of gallium nitride using ZnCl2 as mineralizer
Abstract
Ammonothermal crystal growth of GaN on a HVPE grown GaN seed is realized using ZnCl2 as a novel acidic mineralizer. Compared with other NH4X acidic mineralizers (X: Cl, Br and I), ZnCl2 provides significantly increased crystal growth speed and improved crystal quality under milder operating conditions.
