Majority Carrier Concentration in Semiconductor Solution

STEP 0: Pre-Calculation Summary
Formula Used
Majority Carrier Concentration = Intrinsic Carrier Concentration^2/Minority Carrier Concentration
n0 = ni^2/p0
This formula uses 3 Variables
Variables Used
Majority Carrier Concentration - (Measured in 1 per Cubic Meter) - Majority Carrier Concentration is the number of carriers in the conduction band with no externally applied bias.
Intrinsic Carrier Concentration - (Measured in 1 per Cubic Meter) - Intrinsic Carrier Concentration is the number of electrons in the conduction band or the number of holes in the valence band in intrinsic material.
Minority Carrier Concentration - (Measured in 1 per Cubic Meter) - Minority Carrier Concentration is the number of carriers in the valence band with no externally applied bias.
STEP 1: Convert Input(s) to Base Unit
Intrinsic Carrier Concentration: 120000000 1 per Cubic Meter --> 120000000 1 per Cubic Meter No Conversion Required
Minority Carrier Concentration: 91000000 1 per Cubic Meter --> 91000000 1 per Cubic Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
n0 = ni^2/p0 --> 120000000^2/91000000
Evaluating ... ...
n0 = 158241758.241758
STEP 3: Convert Result to Output's Unit
158241758.241758 1 per Cubic Meter --> No Conversion Required
FINAL ANSWER
158241758.241758 1.6E+8 1 per Cubic Meter <-- Majority Carrier Concentration
