摘要

We study resonant magnetotunneling in the double-barrier heterostructure in the sequential tunneling picture. The effects arising from charge buildup in the well are considered by as-suming that the quasibound energy in the weJJ varies Jin ear ly with the applied bias. Under appropriate approximations, the tunneling current density and the corresponding differen-tial conductance are derived analytically. The results for the peak positions in differential conductance and the threshold current position are consistent with experiments.
