6- A silicon pnp transistor has impurity concentrations of 5 x 1018 cm3, 7 x 1016 cm-3, and 2 × 1016 cm-3 in the emitter, base and collector, respectively. The base width is 1.0 ?m, and the device cross-sectional area is 0.2 mm2. When the emitter-base junction is forward biased to 0.5 V and the base-collector junction is reverse biased to 5 V, calculate the neutral base width and the minority...
