Question

2. Schottky junction:

a. Consider a Schottky junction diode between Au and n-Si doped with 10^16 donors per cubic centimeter. Given the work function of Au at 5.1 eV and the electron affinity of Si is 4.05 eV. What is the theoretical barrier height for electrons from the metal to the semiconductor, and what is the built-in voltage?

b. Draw the equilibrium band diagram of a Al/p-Si Schottky contact. Given the work function of Al at 5.3 eV, what is the theoretical barrier height for holes from the metal to the semiconductor?
