Example 3.1  print file in PDF format

Consider a chrome-silicon metal-semiconductor junction with Nd = 1017 cm-3. Calculate the barrier height and the built-in potential. Repeat for a p-type semiconductor with the same doping density.

Example 3.2  print file in PDF format

Consider a chrome-silicon metal-semiconductor junction with Nd = 1017 cm-3. Calculate the depletion layer width, the electric field in the silicon at the metal-semiconductor interface, the potential across the semiconductor and the capacitance per unit area for an applied voltage of -5 V.
