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.
