Effect of additional HCl flow on the surface morphology of GaN grown on sapphire by HVPE
The effect of additional HCl on the surface morphology of HVPE GaN was investigated. The introduction of additional HCl to the growth zone altered the polar growth direction at the initial growth stage, and finally the Ga-face polarity GaN films with smooth surface were obtained.
