Abstract
In this paper, we reviewed the current development and patents for the application of high-brightness and highefficiency white light-emitting diode (LED). The high-efficiency GaN nanostructures, such as disk, pyramid, and rod were grown on LiAlO2 substrate by plasma-assisted molecular-beam epitaxy, and a model was developed to demonstrate the growth of the GaN nanostructures. Based on the results, the GaN disk p-n junction was designed for the application of high brightness and high efficiency white LED.
Keywords: GaN, light-emitting diode, LiAlO2
