【 摘 要 】

Dependences of the depletion widths in a radial core-shell p-n diode on the radius of metallurgical boundary of the p-n junction have been studied theoretically in detail. While the depletion width of the core increases with decreasing the radius, the depletion width of the shell, on the contrary, decreases. This is the consequence of cylindrical symmetry of the structure. And the total depletion width of the p-n junction can both increase and decrease depending on doping levels of the core and shell. A number of cases is presented where the dependence of depletion width of the p-n junction on its curvature influences on the diode current-voltage characteristics.
