Abstract
𝑀-plane GaN thin films were grown on LiAlO2substrates under different N/Ga flux ratios by plasma-assisted molecular beamepitaxy. An anisotropic growth of𝑀-plane GaN was demonstrated against the N/Ga flux ratio. As the N/Ga flux ratio decreasedby increasing Ga flux, the GaN surface trended to a flat morphology with stripes along[1120]. According to high-resolution X-raydiffraction analysis, Li5GaO4was observed on the interface between GaN and LiAlO2substrate. The formation of Li5GaO4wouldinfluence the surface morphology and crystal quality.
