Optical and electronic properties of a two-dimensional quantum dot with an impurity

  title={Optical and electronic properties of a two-dimensional quantum dot with an impurity},
  author={Tairong Chen and Wenfang Xie and Shijun Liang},
The binding energy and photoionization cross-section (PCS) in a two-dimensional pseudopotential, parabolic potential plus an inverse squared potential, quantum dot (QD) with a donor impurity subjected to a uniform magnetic field directed with respect to the z-axis have been investigated within the compact-density matrix formalism. The dependence of these optical properties on the confinement frequency of the parabolic potential, on the magnetic field and on the external field is studied in… CONTINUE READING
