Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | In this paper, the electrostatic theory of the nanowire radial core-shell -- homojunction has been considered. The calculations carried out show that, in contrast to a planar -- diode, the built-in electric field of the nanowire radial -- diode proves to be inhomogeneous. This field reaches its maximum in the region of the i-layer adjoining the core. When moving away the i-layer from the nanowire center, the degree of field inhomogeneity decays, and both edge values of the field in the i-layer eventually reach the magnitude, which takes place in an analogous planar -- diode. This magnitude can be both higher and lower than the maximal field in the nanowire -- diode (depending on doping conditions). Simultaneously, the capacitance of the nanowire p-i-n diode can both increase and decrease in its value, going, at the same time, to weak voltage dependence inherent to the planar -- diode.
