Abstract
A quantum wire subjected to electric and step-like magnetic fields is numerically studied. Electron energy spectrum and eigenstates are calculated using effective mass approximation. We find an electric field causes crossing and anticrossing behaviours of energy spectrum which are associated with the occurrence of bonding and antibonding states. For ballistic transport, the electron conductance exhibits stepwise variation with some peaks and dips. The conductance character is interpreted by analyzing energy dispersion.
