How to Calculate and Solve for Electrical Conductivity for Intrinsic Semiconductor | Electrical Properties
Last Updated on August 11, 2022
The image of electrical conductivity for intrinsic semiconductor is shown below.
To compute for electrical conductivity for intrinsic semiconductor, five essential parameters are needed and these parameters are Number of Holes (p), Number of Free Conducting Electrons (n), Hole Mobility (μh), Electron Mobility (μe) and Electrical Charge (e).
The formula for calculating electrical conductivity for intrinsic semiconductor:
σ = n|e|μe + p|e|μh
Where:
σ = Electrical Conductivity for Intrinsic Semiconductor
p = Number of Holes
n = Number of Free Conducting Electrons
μh = Hole Mobility
μe = Electron Mobility
e = Electrical Charge
Let’s solve an example;
Find the electrical conductivity for intrinsic semiconductor when the number of holes is 14, the number of free conducting electrons is 12, the hole mobility is 8, the electron mobility is 4 and the electrical charge is 2.
This implies that;
p = Number of Holes = 14
n = Number of Free Conducting Electrons = 12
μh = Hole Mobility = 8
μe = Electron Mobility = 4
e = Electrical Charge = 2
σ = n|e|μe + p|e|μh
σ = (12)|2|(4) + (14)|2|(8)
σ = (12)(2)(4) + (14)(2)(8)
σ = 96 + 224
σ = 320
Therefore, the electrical conductivity for intrinsic semiconductor is 320 S/m.
