Question: A step pn junction diode having Na=10¹⁶/cm³ and Nd = 4 x 10¹⁸/cm³ values was false

A step pn junction diode having Na=10¹⁶/cm³ and Nd = 4 x 10¹⁸/cm³ values was fabricated.

T = 300K, applied voltages VA = -3 and 0.4V were respectively applied. ni=1.5x1010/cm³.

a. Check if the low-level injection condition is satisfied when the forward voltage 0.4 V is applied.

b. Calculate how the magnitude of the energy barrier between p- and n-type semiconductors changes when forward and reverse voltages are applied

c. VA = -3 and 0.4V: Calculate the width(W) of the depletion layer in each of these conditions and explain the result.

d. Calculate and plot how the electric field, E(x), changes when forward and reverse voltages are applied.
