论文摘要
我们研究了单层钼二硫化物量子点MOS2的圆形量子点中的潜在质量点中的狄拉克电子散射问题。通过求解狄拉克的方程，我们为特征态，散射系数，散射效率和反射电流的径向分量制定分析表达式。我们表明，反射电流的散射系数，散射效率和径向分量明确取决于磁通量。磁通量可能会导致散射系数的振荡位置略有变化。为了散射效率，磁通量也可能导致其振荡位置略有变化，当磁通量降低时振幅增加。
We study the Dirac electron scattering problem on a potential barrier in a circular quantum dot of Monolayer Molybdenum Disulfide quantum dot MoS2 subjected to magnetic flux. By solving Dirac's equation, we formulate analytical expressions for the eigenstates, scattering coefficients, scattering efficiency, and the reflected current's radial component. We show that the scattering coefficients, the scattering efficiency, and the radial component of the reflected current depend explicitly on the magnetic flux. The magnetic flux may cause a slight shift in the oscillation position of the scattering coefficients. For scattering efficiency, magnetic flux may also lead to a slight shift in their oscillation position and an increase in amplitude when the magnetic flux decreases.
