Step 1 of 2 3.015P The charge stored in one side of the junction is, Substitute C for q, which represents charge of an electron for which represents doping concentration on one side of the junction 10 µm² for A, which represents cross sectional area of the junction 0.2 for W, which represents width of the depletion region = Therefore, the charge stored in one side of the junction is Step 2 of 2 The built in voltage of the junction V₀ is, = Square the equation on both sides. Substitute F/cm permittivity of free space = F/cm Substitute C for ,10 µm² for A C for q for for V. = = 3.1 V Therefore, the built in voltage value is 3.1V
