Theory of the Raman-scattering intensity and line shape of a quantum-dot superlattice

Journal Article


Abstract


  • The Raman-scattering cross section of a quantum-dot superlattice is calculated. It is found that the interdot Coulomb interaction plays an important role in both the excitation energy and the scattering cross sections. It is shown that the oscillator strengths of the induced electron-electron- interaction-coupled modes are strongly magnetic-field dependent. The effect due to van Hove singularities in the joint density of states of pair excitations on the scattering intensity and line shape is also discussed. © 1991 The American Physical Society.
