WebThe minority carrier lifetime of a material, denoted by τ n or τ p, is the average time which a carrier can spend in an excited state after electron-hole generation before it recombines. It is often just referred to as the "lifetime" and has nothing to do with the stability of the material. Stating that "a silicon wafer has a long lifetime ... WebAlso, µn and µp are the minority-carr ier moblities of electrons and holes. We have sown in previous paper that the long-term decay of excess majority carriers in a p-n device is: ∆ n(t)=∆0 exp −qJ0t KTC ⎛ ⎝ ⎜ ⎞ ⎠ ⎟ (2) Here, J0 is the reverse saturation current of the p-n device, and C is the junction capacitance.

"WebPN junctions are fabricated from a monocrystalline piece of semiconductor with both a P-type and N-type region in proximity at a junction. The transfer of electrons from the N side of the junction to holes annihilated on the P side of the junction produces a barrier voltage. This is 0.6 to 0.7 V in silicon and varies with other semiconductors. " - Pn minority's

WebSemiconductors contain majority and minority carriers. The more abundant charge carriers are the majority carriers; the less abundant are the minority carriers. The equilibrium carrier concentration can be increased through doping. The total number of carriers in the conduction and valence band is called the equilibrium carrier concentration.
