项目摘要

Blue, green and white light emitting diodes and violet laser diodes on sapphire substrates have been already commercialized which are based on the low temperature buffer layer technology developed by us. Applications of nitride semiconductors are not limited to visible range, but can be applied to ultraviolet range. Expected applications of solid state UV/DUV light emitters/detectors include sterilizer, DNA analyzer, laser knife, flame sensor, dermatology, molecular tweezers, weather observation, gas decomposition, photolithography, etc. Formerly, AlN was grown at or lower than 1,200□ on other materials such as sapphire or SiC. Our previous mass transport study showed that in order to achieve sufficient migration of Al precursor, AlN should be grown higher than 1,200□.The objective of this study is as follows ;(1)Growth of AlN substrate by sublimation(2)Growth of AlN on sapphire by metalorganic vapor phase epitaxy (MOVPE) at high temperature, and(3)Fabrication of high quality AlGaN-based quantum structure and UV emitting deviceIn 2003, custom designed MOVPE reactor which is capable of raising temperature as high as 1,800□ was installed and operated with the cooperation of Ibiden Co.,Ltd. Sublimation growth of AlN on SiC and spontaneous nucleation was performed. In 2004, world's shortest wavelength laser diode on sapphire was successfully fabricated on epitaxially lateral overgrown (ELO) low dislocation density AlGaN. High quality and thick AlN was grown on sapphire by high temperature MOVPE. In 2005, we successfully grow low dislocation density AlN on sapphire using ELO technique with a dislocation density as low as 10^7cm^<-2> or less.
蓝宝石衬底上的蓝、绿色和白色发光二极管和紫色激光二极管已经商业化,这是基于我们开发的低温缓冲层技术。氮化物半导体的应用不限于可见光范围,而是可以应用于紫外线范围。固态UV/DUV光发射器/检测器的预期应用包括灭菌器、DNA分析仪、激光刀、火焰传感器、皮肤病学、分子镊子、天气观测、气体分解、光刻等。我们之前的质量传输研究表明,为了实现Al前驱体的充分迁移,AlN的生长应该高于1,200 □。(1)通过升华法生长AlN衬底(2)通过金属有机气相外延(MOVPE)在高温下在蓝宝石上生长AlN,以及(3)制造高质量AlGaN基量子结构和UV发射器件2003年,定制设计的MOVPE反应器能够将温度升高到1,800 ℃,在Ibiden Co.的合作下安装和操作,进行了AlN在SiC上的升华生长和自发形核。2004年,世界上最短波长的蓝宝石激光二极管在外延横向过生长(ELO)低位错密度AlGaN上成功制造。采用高温MOVPE法在蓝宝石衬底上生长出了高质量、厚膜的AlN。2005年,我们成功地使用ELO技术在蓝宝石上生长了位错密度低至10^7cm^或更低的低位错密度AlN<-2>。
