The formation of tapered self-catalyzed nanowires grown on reflecting substrates is studied theoretically. Within the model, the nanowire radius may be obtained as a function of length. The model describes the morphology of tapered nanowires. We study the influence of different growth parameters, including the III/V flux ratio and pitch, on the nanowire morphology. Keywords: III-V nanowires, morphology, self-focusing effect, modeling
