Utilizing the tight-binding method, we investigate the electronic and optical properties of the zigzag hexagonal silicene quantum dots (ZHSQDs) subjected to a perpendicular magnetic field. The edge states emerge in the energy gap as the size of ZHSQDs increases. In the presence of spin–orbit coupling (SOC), the corresponding energy levels of edge states oscillate with magnetic flux. The reason is that the energy levels of silicene quantum dots are splitted in the presence of SOC. In addition, the optical absorption peak undergoes blue shift as the strength of SOC increases, and the optical absorption mainly occurs between the Landau levels in the presence of magnetic field.

利用紧密结合的方法，我们研究了在垂直磁场下曲折六边形硅量子点（ZHSQDs）的电子和光学性质。随着ZHSQD尺寸的增加，边沿状态出现在能隙中。在存在自旋轨道耦合（SOC）的情况下，边缘状态的相应能级随磁通量振荡。原因是硅的量子点的能级在存在SOC时分裂。另外，随着SOC的强度增加，光吸收峰经历蓝移，并且在存在磁场的情况下，光吸收主要发生在朗道能级之间。
