Abstract :
A model based on the experimental results has been proposed in this work to interpret the lateral growth feature and its effect on the optical properties of GaN epitaxial layers. Under the high lateral growth rate, dislocation located at the grain boundaries is easy to bend into the inner parts of grains, which will deteriorate the light extraction efficiency of the film.
