中文摘要 | We report theoretical investigations on how edge states are destroyed in disordered mesoscopic samples by calculating a "phase diagram" in terms of energy versus disorder strength (E,W), and magnetic field versus disorder strength (B,W), in the integer quantum Hall regime. It is found that as the disorder strength W increases, edge states are destroyed one by one if transmission eigenchannels are used to characterize the edge states. Near the insulating regime, transmission eigenchannels are closed one by one in the same order as edge states are destroyed. To identify those edge states which have survived disorder, we introduce a generalized current density that can be calculated and visualized. |
