Experimental Values

Studying the quantum size effects on the exciton energy of two-dimensional CdS quantum dots in the single band effective mass approximation for both electron and hole, we use a finite confinement in the x–y plane and we assume also that the induced charge is spread along a very thin interface in the z-direction. Solving the Schrödinger equation with a new numerical method, which is called potential morphing method, we obtain the corresponding energy within the self-consistent Hartree scheme. Excellent agreement is obtained with the experimental values of exciton energies for various sizes of CdS quantum dots in the strong, medium and weak confinement limit.

Far Infrared Spectra

The energy levels and far-infrared spectra of two electrons confined in quantum dots and quantum rings under a magnetic field have been investigated. The size and shape effects of quantum rings on the levels and the spectra are clearly revealed. It is found that the spin oscillation of two electrons in a quantum ring with a magnetic field is caused by the Coulomb interaction. The transitions of two-electron far-infrared spectra are clearly shown from quantum dots to quantum rings. The influence of electron–electron interaction on the energy levels and far-infrared spectra has been discussed. The quantum size effects predict a possibility to observe phenomena related to electron-electron interaction in quantum rings.
