由二维导体的边对边结构组成的量子交叉系统有望成为分子电子器件的理想平台。作为第一步，我们已经计算了电子能谱的二维电子气在GaAs/AlGaAs异质界面作为候选的二维导体在量子交叉，考虑到电子相关的二维电子系统。结果，我们证实了等离子体可以稳定存在。这意味着当我们测量量子交叉器件的电流-电压特性时，我们将观察到由于等离子体激元诱导的散射而导致的电导峰的加宽。
A quantum cross system consisting of the edge-to-edge configuration of two-dimensional (2D) conductors is expected to serve as an ideal platform for molecular electronic devices. As the first step, we have calculated the electron energy spectrum of 2D electron gas at a GaAs/AlGaAs heterointerface as a candidate for the 2D conductor in the quantum cross, taking into consideration the electron correlation for the 2D electron system. As a result, we have confirmed that a plasmaron can exist stably. This means that we will observe the broadening of the conductance peak due to the scattering induced by plasmons when we measure the current–voltage characteristics of the quantum cross device.
