How to Calculate and Solve for Electrical Conductivity for Extrinsic p-type Semiconductor | Electrical Properties
Last Updated on August 11, 2022
The electrical conductivity for extrinsic p-type semiconductor is illustrated by the image below.
To compute for electrical conductivity for extrinsic p-type semiconductor, three essential parameters are needed and these parameters are Number of Holes (p), Hole Mobility (μh) and Electrical Charge (e).
The formula for calculating electrical conductivity for extrinsic p-type semiconductor:
σ ≅ p|e|μh
Where:
σ = Electrical Conductivity for Extrinsic p-type Semiconductor
p = Number of Holes
μh = Hole Mobility
e = Electrical Charge
Let’s solve an example;
Find the electrical conductivity for extrinsic p-type semiconductor when the number of holes is 24, the hole mobility is 12 and the electrical charge is 4.
This implies that;
p = Number of Holes = 24
μh = Hole Mobility = 12
e = Electrical Charge = 4
σ ≅ p|e|μh
σ ≅ (24)|4|(12)
σ ≅ (24)(4)(12)
σ ≅ 1152
Therefore, the electrical conductivity for extrinsic p-type semiconductor is 1152 S/m.
Calculating the Number of Holes when the Electrical Conductivity for extrinsic p-type semiconductor, the Hole Mobility and the Electrical Charge is Given.
p = σ / μh(e)
Where:
p = Number of Holes
σ = Electrical Conductivity for Extrinsic p-type Semiconductor
μh = Hole Mobility
e = Electrical Charge
Let’s solve an example;
Find the number of holes when the electrical conductivity for extrinsic p-type semiconductor is 42, the hole mobility is 3 and the electrical charge is 1.
This implies that;
σ = Electrical Conductivity for Extrinsic p-type Semiconductor = 42
μh = Hole Mobility = 3
e = Electrical Charge = 1
p = σ / μh(e)
p = 42 / 3(1)
p = 42 / 3
p = 14
Therefore, the number of holes is 14.
Calculating the Hole Mobility when the Electrical Conductivity for Extrinsic p-type Semiconductor, the Number of Holes and the Electrical Charge is Given.
μh = σ / p(e)
Where:
μh = Hole Mobility
σ = Electrical Conductivity for Extrinsic p-type Semiconductor
p = Number of Holes
e = Electrical Charge
Let’s solve an example;
Find the hole mobility when the electrical conductivity for extrinsic p-type semiconductor is 24, the number of holes is 4 and the electrical charge is 2.
This implies that;
σ = Electrical Conductivity for Extrinsic p-type Semiconductor = 24
p = Number of Holes = 4
e = Electrical Charge = 2
μh = σ / p(e)
μh = 24 / 4(2)
μh = 24 / 8
μh = 3
Therefore, the hole mobility is 3.
Calculating the Electrical Charge when the Electrical Conductivity for Extrinsic p-type Semiconductor, the Number of Holes and the Hole Mobility is Given.
e = σ / μh(p)
Where:
e = Electrical Charge
σ = Electrical Conductivity for Extrinsic p-type Semiconductor
p = Number of Holes
μh = Hole Mobility
Given an example;
Find the electrical charge when the electrical conductivity for extrinsic p-type semiconductor is 72, the number of holes is 6 and the hole mobility is 2.
This implies that;
σ = Electrical Conductivity for Extrinsic p-type Semiconductor = 72
p = Number of Holes = 6
μh = Hole Mobility = 2
e = σ / μh(p)
e = 72 / 2(6)
e = 72 / 12
e = 6
Therefore, the electrical charge is 6.
