Calculation of Conductivity of Semiconductor
The conductivity of a semiconductor can be calculated using the formula:
σ = q * (n * μn + p * μp)
Where:
σ = conductivity
q = charge of an electron (1.6 x 10^-19 C)
n = electron concentration (0.45 x 10^12 m^-3)
μn = electron mobility (0.135 m^2V^-1S^-1)
p = hole concentration (5.0 x 10^20 m^-3)
μp = hole mobility (0.048 m^2V^-1S^-1)
Calculation
1. Calculate the contribution of electrons to conductivity:
n * μn = 0.45 x 10^12 * 0.135 = 6.075 x 10^10
2. Calculate the contribution of holes to conductivity:
p * μp = 5.0 x 10^20 * 0.048 = 2.4 x 10^19
3. Calculate the total conductivity:
σ = 1.6 x 10^-19 * (6.075 x 10^10 + 2.4 x 10^19) = 3.84
Therefore, the conductivity of the semiconductor is 3.84 in SI units.
