Description
Summary:Based on the phase coherence of electron waves, an analytical method has been proposed to approach the resonant states in mesoscopic devices. The proposed method has been demonstrated that it is valid in the studies of the resonant states in quantum well structures and the ballistic transport in ultrathin MOS devices. The resonant states in mesoscopic devices calculated from the proposed method agree well with those from the quantum mechanical method. The results show that the proposed method is valid in simplifying some quantum issues in mesoscopic devices.
