Reconstruction of electronic filling spectra caused by the deformation in few-electron quantum dots

We present a simple and feasible method based on ab initio principle for studying the partly deformed quantum dot with a three-dimensional confinement potential of finite depth, which relies on the unrestricted Hartree–Fock–Roothaan equation. The results show that the electronic filling spectra can reconstruct due to the deformation effect in few-electron quantum dots. This method can solve few-body problem of the deformed quantum dot and study the geometry effect on the excess electron filling spectra.
