The Fractional-Dimensional Excitonic Absorption Theory Applied to Real V-groove Quantum Wires

A fractional dimensional approach is applied to a realistic V‐groove quantum wire in order to calculate the excitonic absorption spectrum. An excellent agreement is obtained with much more computationally demanding models as well as with experimental photoluminescence excitation data. However, comparison with a full excitonic calculation reveal situations were the concept of fractional dimensions to some extent fails.
