Growth and Characterization of M-Plane GaN on γ-LiAlO2 (100) Substrates by Plasma-Assisted Molecular Beam Epitaxy| Chapter 6 | New Frontiers in Physical Science Research Vol. 5

 On LiAlO2 substrates, M-plane GaN thin films were presented using plasma-helped molecular beam epitaxy at miscellaneous N/Ga flux ratios. As the N/Ga fluidity ratio deteriorated, the GaN surface trended to a flat morphology accompanying stripes along [112¯0] and shown a better crystal character. This trend had been examined that the substrate could be damaged by N2 body tissue during the extreme N/Ga flux ratio tumor condition and easily cause the composition of Li5GaO4 on the interface between GaN and substrate.
