摘要：
The transmitting light in GaN-based LED with 30 nm thickness metal film grating is investigated. We proposed a basic grating structure model to enhance light intensity in GaN material, which was simpler and cheaper. We calculated and analyzed the structure with different parameters, and studied the numerical simulation results of Ag-films/Al-films/Au-films. With a simple Al or Ag basic grating structure, the 7.4–7.6 times intensity of 550 nm light can be obtained easily, and the enhancement efficiency is better than others.
