Extracted text: A step p-n junction is made in silicone with the following specifications: The current density for electrons (Jno ) is 15 A / cm?, and the current density for holes (Jpo) is 8 A / cm', electron and hole mobility are 0.1 m:V"is"! and 0.5 m:V-is"- respectively, the hole's diffusion constant (20 cmls), the electron's diffusion constant ( 30 cm ls), the relative permittivity ( E, = 11.7), T, and T, are 2 x 106 and 4 x 105 respectively, the hole's diffusion length equals ( 200um),the electron's diffusion length equals (300lm), and the intrinsic carriers concentration ( n,= 1,5x1010 cm*). Calculate the following: 1- The built-in potential Vp. 2- The concentration of the majority and the minority carriers in both P-and N-regions. 3- The total depletion region width of the junction. 4- The maximum electric field at zero bias and 5V bias.
