摘要Keldysh's nonequilibrium Green's function is applied to studying resonant magnetotunneling through a quantum dot. We propose a microscopic Anderson-impurity-like Hamiltonian in which two kinds of the on-site Coulomb interactions are introduced: the interaction of two electrons at the same Landau level with different spins, U, and the interaction for the electrons between different Landau levels, U-1. I-V curves are obtained under different magnetic fields in asymmetrical structures which can display both the energy quantization and single-electron charging effect. The theoretical results are in good agreement with the experiments quantitatively. The Linear-response conductance is also discussed.
