Abstract
The influence of the circular geometry of a p-n junction built into a nanowire or a nanorod, on the radial diode current density is investigated. While the current density from the core to the shell proves to be larger than that in a planar diode at the same values of the parameters, the density of the diode current from the shell to the core, on the contrary, proves to be smaller. A dependence of the effect on the core and the shell radii has been demonstrated. The nature of the effect is explained on the basis of radial distributions of the nonequilibrium current carriers.
