Studying quantum effects in nitride-based nanowires with diameters scaling down to a few hundred nanometers is hindered by their still mostly bulk-like properties. A drastic diameter reduction towards the domain of the so-called quantum wires (QWRs) facilitates true one- dimensionality of the structures exhibiting confinement in two directions, while the third direction can straightforwardly be tailored. If the QWR length is sufficiently reduced one can approach the transitional regime between one- and zero-dimensional structures with drastic effects on the observed emission line characteristics and photon statistics.
Our results summarize the particular optical properties of novel GaN QWRs with special regard on the photon statistics. By tuning the QWR length as most vital parameter we can tune the emission characteristics yielding a natural transition between the optical properties of one- to zero-dimensional structures with strong perspectives for future photonic applications.
