中文摘要
高质量的GaN晶体是制备节能发光器件和大功率器件的关键材料。本研究中,通过热力学分析和第一性原理计算发现了一种新的源分子,并将其作为氢化物气相外延的前驱体。实际上,GaN的生长发生在1200 ℃,并且生长速率变得大于200微米/小时。
英文摘要
High quality crystal of GaN is a key material promising for energy-saving light emitting and high-power devices. In the study, a new source molecule, which was found out by the thermocynamic analysis and first principle calculation, was used as precursor for hydride vapoe phase epitaxy. Actually, the growth of GaN occured at 1200 C and the growth rate became more than 200 micron-m/hr.
