We demonstrate in this work the effects of flow modulation on the crystalline quality and morphology of GaN epilayers grown by hydride vapor phase epitaxy. The improvement in the structural qualtiy is attributed to the strain relaxation, dislocations suppression and enhanced Ga diffusion.
## Abstract Epitaxial layers of monoclinic Ξ²βGa~2~O~3~ were successfully grown on (0001) sapphire and ($ \bar 1 $11)~As~ GaAs substrates using metalβorganic vaporβphase epitaxy (MOVPE). Triethylgallium (TEGa) and N~2~O were used as precursors for gallium and oxygen, respectively. Growth conditions
