Resumen

Binding energy of Wannier excitons in a quantum well of thickness L is studied using two models: a two-parameter trial wave function and a fractional-dimensional space with dimension 2 ≤ α ≤ 3. Since both models provide quantitative measures of the exciton spatial anisotropy as L changes, we give physical arguments for a plausible definition of α = α(L).
