Make sure you label the individual parts clearly. FRQ#4. Metal-semiconductor contacts (13 points) A Schottky contact is formed between a metal with a work function of 4.5 eV and a p-Si in which the Fermi level is 0.2 eV away from the nearest band edge. The bandgap of Si is 1.12 eV and the electron affinity of Si is 4.05 eV. (1) Draw the equilibrium band diagram of this metal-semiconductor contact. Label the Fermi energy of both materials and the conduction/valence band edges of p-Si. (4 points) (2) Calculate the built-in potential across this Schottky contact. (3 points) (3) Calculate the Schottky barrier height for hole injection from metal to semiconductor in this Schottky contact. (3 points) (4) Explain why a Schottky contact has a rectifying current behavior under bias. (3 points)
