A Si sample is doped with $5 \times 10^{17}$ As atoms/cm$^3$. What is the equilibrium hole concentration $p_0$ at 300 K? Where is $E_F$ relative to $E_i$? If $n_i$ at T is equal to $N_d$, what is the expression for $n_0$ and $p_0$ at T?

A Si sample is doped with 10^17 As atoms/cm^3. What is the equilibrium hole concentration p0 at 300 K? Where is EF relative to Ei? SOLUTION Since Nd >> ni, we can approximate n0 = Nd and p0 = ni^2 / n0 = (2.25 x 10^20) / 10^17 = 2.25 x 10^3 cm^-3 From Eq. (3-25a), we have EF - Ei = kT ln(n0/ni) = 0.0259 ln(10^17 / (1.5 x 10^10)) = 0.407 eV The resulting band diagram is:
