论文摘要
与强度函数现象和巨大共振有关的门道状态是在两个系统相互作用时就会出现的，一个是具有高密度特征值光谱的，另一个具有相对较低的密度。这些概念是在40年代首次研究的，在这里从特殊和简单的石墨烯结构中的理论观点分析，在将适当的电压应用于石墨烯片后获得。还研究了门口状态对这些系统中电子传输的影响。为了分析这些效果，我们考虑了一个二维模型，该模型的高度相等，但宽度非常不同。
Doorway states, which are related to the strength function phenomenon and giant resonances, arise when two systems interact, one with a high density eigenvalue spectrum and the other with a comparatively low density. These concepts, first studied in nuclear physics in the 40's, are here analyzed from a theoretical point of view in special and simple graphene structures, obtained after applying appropriate voltages to a graphene sheet. The influence of the doorway states on the electronic transport in these systems is also studied. To analyze these effects we consider a two-dimensional model of two potential barriers of equal height but very different widths separated by a well.
