Excess Carrier Concentration Solution

STEP 0: Pre-Calculation Summary

Formula Used

Excess Carrier Concentration = Optical Generation Rate*Recombination Lifetime
δ_n = g_op*τ_n
This formula uses 3 Variables

Variables Used

Excess Carrier Concentration - (Measured in 1 per Cubic Meter) - Excess Carrier Concentration is extra of electron present in the carrier concentration.
Optical Generation Rate - Optical Generation Rate the number of electrons generated at each point in the device due to the absorption of photons.
Recombination Lifetime - (Measured in Second) - Recombination Lifetime the average time it takes an excess minority carrier to recombine.

STEP 1: Convert Input(s) to Base Unit

Optical Generation Rate: 2.9E+19 --> No Conversion Required
Recombination Lifetime: 3.62E-06 Second --> 3.62E-06 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

δ_n = g_op*τ_n --> 2.9E+19*3.62E-06

Evaluating ... ...

δ_n = 104980000000000

STEP 3: Convert Result to Output's Unit

104980000000000 1 per Cubic Meter --> No Conversion Required

FINAL ANSWER

104980000000000 ≈ 1E+14 1 per Cubic Meter <-- Excess Carrier Concentration
