圆形石墨烯pn结中负Refractive Index引起的焦散线
Caustics due to Negative Refractive Index in Circular Graphene p-n Junctions
摘要:
我们发现,波函数在圆形石墨烯pn结中形成焦散线,在几何光学的框架下,可以用负折射率来解释。
英文摘要:
We show that the wavefunctions form caustics in circular graphene p-n junctions which in the framework of geometrical optics can be interpreted with negative refractive index.
