How minority charge carriers are distributed in BJT?

The physical operation of the BJT can be enhanced by considering the distribution of minority charge carriers in the base and the emitter. The profiles of the concentration of electrons in the base and holes in the emitter of an NPN transistor operating in the active mode. Observe that since the doping concentration in the emitter, ND, is much higher than the doping concentration in the base, NA, the concentration of electrons injected from emitter to base, n p(0), is much higher than the concentration of holes injected from the base to the emitter, pn(0). Both quantities are proportional to evBE /VT.

How to Calculate Concentration of electrons injected from emitter to base?

Concentration of electrons injected from emitter to base calculator uses Concentration of e- injected from emitter to base=Thermal Equilibrium Value*e^(Voltage across the base–emitter junction/Thermal voltage) to calculate the Concentration of e- injected from emitter to base, The concentration of electrons injected from emitter to base is the number of electrons that is transferred from the emitter region of the transistor to the base region of the transistor. Concentration of e- injected from emitter to base and is denoted by np symbol.

FAQ

What is Concentration of electrons injected from emitter to base?
The concentration of electrons injected from emitter to base is the number of electrons that is transferred from the emitter region of the transistor to the base region of the transistor and is represented as np=npo*e^(VBE/Vt) or Concentration of e- injected from emitter to base=Thermal Equilibrium Value*e^(Voltage across the base–emitter junction/Thermal voltage). Thermal Equilibrium Value is the value of the thermal equilibrium of the minority-carrier (electron) concentration in the base region, The voltage across the base–emitter junction is the forward voltage between the base and emitter of the transistor and Thermal Voltage is the voltage produced within the p-n junction.
