本文报道了银稳定的正则阶梯晶格在附近的Si(111)错切向[112]方向的形成。通过单畴Si(111)-(3×1)-Ag重构,避免了清洁表面的阶跃聚束特性。该纳米结构表面被用作模板,用于生长尺寸为1 nm的银量子点的一维阵列,沿行的择优间距为1.5 nm。
The formation of a Ag-stabilized regular step lattice on vicinal Si(111) miscut towards [112] is reported. The step bunching characteristic of the clean surface is prevented by single-domain Si(111)-(3×1)-Ag reconstruction. The nanostructured surface is used as a template for growing one-dimensional arrays of 1 nm sized Ag quantum dots with a preferential spacing of 1.5 nm along the rows.
