文摘

We make a comparative study on the energy levels of the phosphorene quantum dots and rings. The energy levels can be anisotropically controlled by the electric field and the strains, different from those in graphene counterparts. The edge states in phosphorene triangular quantum dot and rings are anisotropic. A helpful reference for understanding phosphorene nanostructures of other shapes and designing devices.
