An ideal metal-semiconductor contact is made of a metal that has ?M=4.75 eV, and a semiconductor that has ?=4.00 eV with ni=1010/cm3, ND=1016/cm3, and EG=1.00 eV; kT=0.026 eV.

(a) Calculate the barrier for electrons in the metal.

(b) Calculate Vbi, the barrier for electrons in the semiconductor.

(c) Calculate the value of the depletion region width at thermal equilibrium.

(d) Calculate the maximum electric field.

(e) Sketch the energy band diagram in thermal equilibrium.
