20150225874 | METHOD FOR GROWING ZIRCONIUM NITRIDE CRYSTAL - According to the present invention, if a zirconium nitride lattice is grown by a method for growing zirconium nitride using a metal-organic vapor phase epitaxy method, the lattice binding efficiency of ZrN and GaN can enable a low cost preparation of an LED having high performance and it is very advantageous to grow a green LED by a direct band gap in the presence of Zr3N4. In addition, InZr3N4 can be substituted for In when growing a MQW in an LED, and thus it is very advantageous to prepare green and red LEDs. Further, a more satisfactory diffusion current can be obtained using ZrN or Zr3N4 as an epitaxial interlayer, and thus it is very advantageous in the application of a large LED chip and it is possible to prevent thermal expansion or cracks with respect to a silicon substrate. | 08-13-2015 |
