- W1994838863 abstract "Abstract We have calculated the binding energy and oscillator strength of screened two-dimensional excitons in a semiconducting quantum well structure as a function of the screening parameter q s . The calculations involved solving exactly the two-dimensional Schrodinger equation for electrons and holes interacting via a screened 2D Coulomb potential using a numerical Sturm-Liouville eigenvalue solver, SLEIGN. This enabled us to obtain the exact binding energy and oscillator strength of screened 2D excitons in these structures for the first few exciton levels. The binding energy and the oscillator strength are both found to decrease with increasing values of the screening parameter q s . For arbitrary values of the screening parameter, the ground state of the exciton remains bound although the binding energy becomes arbitrarily small. However, calculations of the energies of some of the higher lying exciton states show that they become unbound at finite values of the screening parameter. Also, the oscillator strengths for both the ground and excited exciton states are found to decrease with increasing screening." @default.
