摘要：

The effect of an artificial impurity on electronic properties of interacting electron droplets in quantum dots in a strong magnetic field is studied using Hartree-Fock approximation and exact diagonalization techniques. Introduction of an attractive/repulsive impurity in the spin-polarized droplet induces electronic spin and charge transitions. We show how these spin-related transitions can be observed in resonant tunneling through quantum dots. © 1995 The American Physical Society.
