In this study, a new method for synthesizing single‐crystal ring‐like β‐Ga 2 O 3 nanobelts (here named nanorings), of only 0.2–1 µm in diameter, is presented. A microwave plasma method involving liquid‐phase gallium containing H 2 O in an Ar atmosphere, using silicon as the substrate, is used for the first time. The morphology and structure of the nanorings were analysed using scanning electron microscopy and X‐ray diffraction. The morphology of β‐Ga 2 O 3 nanobelts was also characterized using transmission electron microscopy (TEM) and high‐resolution TEM in order to propose possible growth mechanisms of the β‐Ga 2 O 3 nanorings.
