where Nc and Nv are the effective densities of states in the conduction and valence bands, respectively, Eg is the bandgap energy, k is the Boltzmann constant, and T is the temperature.

Vtn = 0.5 V γ = 0.5 V^1/2 φf = 0.3 V Vsb = 0 V

2.1 Calculate the built-in potential barrier in a pn junction. Advanced Semiconductor Fundamentals Solution Manual

ni ≈ 1.45 x 10^10 cm^-3

Vth = Vtn + γ * (√(2φf + Vsb) - √(2φf)) where Nc and Nv are the effective densities

The electron and hole mobilities in silicon at 300 K are:

Vbi = (kT/q) * ln(Na * Nd / ni^2)

Substituting typical values:
