Question-1: At a forward bias of 0.2 V, calculate the minority electron
concentration at the junction edge (or depletion edge) of the p-type. Assume
that the minority electron concentration at equilibrium is n_{p0}
= 1000 electrons/cm^{3} and use the formula n_{p} = n_{p0}
exp(V/V_{T}) where V_{T} = 0.025 V at room temperature.

Answer:

V=0.2 Volts: **n _{p}** = n
