4. A Si P*N diode is doped with NA (NA>> n¡) in P and Np (Np>> ni) in N. The resistivity of the N- region is 1 Ocm. What would be the resistivity of the P-region if 99% of the total width of the space charge region would be located on the N side? Assume carrier mobilities do not change with the doping density and u,= 1500, up=500.

Diode current and temperature. At normal operating conditions, the current-voltage relation for a diode (p-n semiconductor junction) is given by eV 1 (V) - Is (exp (817)-1) = Where kB = 8.617 x 10-5[eV/K] In terms of e, kg, and T, what is a possible range of voltage such that the diode is approximately ohmic (satisfies Ohm's law)?
In PN junction in series with a 100 ohms resistor, is forwarded biased. So that a current of 100 mA flows. If the voltage across this combination is instantaneously reversed at t = 0 current through diode is approximately given by:
