Abstract :
We study the temperature dependence of the emitter saturation current for bipolar devices by varying the surface recombination velocity at the emitter surface. From this dependence we derive a value for the bandgap narrowing that is in better agreement with other determinations than were previous results obtained from the temperature dependence measured on devices with ohmic contacts.
