论文摘要
我们通过电势研究了石墨烯中磁量点中限制在石墨烯中的磁量子点的能量水平。我们解决了两个区域的特征值方程。我们明确确定两个山谷$ k $,$ k'$的特征派纳者,并在量子点接口处使用边界条件来获得能量水平。我们表明,在物理参数的适当条件下,能级表现出对称和不对称行为。已经发现,通过在量子点之外引入能量隙来改变能量水平,会改变电特性。
We investigate the energy levels of charge carriers confined in a magnetic quantum dot in graphene with an inhomogeneous gap through an electrical potential. We solve the eigenvalue equation for two regions. We explicitly determine the eigenspinors for both valleys $ K $, $ K' $ and use the boundary condition at the quantum dot interface to obtain the energy levels. We show that the energy levels exhibit symmetric and asymmetric behavior under appropriate conditions of the physical parameters. It has been found that changing the energy levels by introducing an energy gap outside the quantum dot changes the electrical properties.
