[10p-PB5-35] Shape anisotropy of MoS2 islands grown on vicinal c-sapphire surfaces
Keywords:transition metal dichalcogenide
CVD method is widely used for the synthesis of monolayer TMDC, and alignment of TMDC is reported particularly on a crystal substrate such as sapphire. These shapes are equilateral triangles, and orientations are dependent on the atomic arrangement of the substrate. Therefore, we focused on the step-terrace structure of sapphire and studied the shape anisotropy of single layer MoS2 grown on a slightly tilted sapphire substrate with different from the OFF direction and angle.
