Given data:
Hall coefficient of Si specimen = -7.35 × 10-5m³ C-1
Temperature range = 100 K to 400 K
Conductivity = 200 2-¹m-¹
Determining the type of semiconductor:
The sign of the Hall coefficient gives the information about the type of semiconductor. If the sign of the Hall coefficient is negative, then the semiconductor is an n-type semiconductor. If the sign of the Hall coefficient is positive, then the semiconductor is a p-type semiconductor.
In this case, the Hall coefficient is negative, which means that the semiconductor is an n-type semiconductor.
Calculating the density of charge carriers:
The formula for the density of charge carriers is given by:
n = 1/eRH
where,
n = density of charge carriers
e = electronic charge = 1.6 × 10-19 C
RH = Hall coefficient
Substituting the given values, we get:
n = 1/(1.6 × 10-19 × (-7.35 × 10-5))
n = 8.58 × 10^19 m^-3
Therefore, the density of charge carriers in the n-type Si semiconductor is 8.58 × 10^19 m^-3.
Calculating the mobility of charge carriers:
The formula for the mobility of charge carriers is given by:
μ = σ/ne
where,
μ = mobility of charge carriers
σ = conductivity
n = density of charge carriers
e = electronic charge = 1.6 × 10-19 C
Substituting the given values, we get:
μ = (200 × 10^-4)/(1.6 × 10^-19 × 8.58 × 10^19)
μ = 1.43 × 10^-3 m² V^-1 s^-1
Therefore, the mobility of charge carriers in the n-type Si semiconductor is 1.43 × 10^-3 m² V^-1 s^-1.
In summary:
- The Si specimen is an n-type semiconductor.
- The density of charge carriers is 8.58 × 10^19 m^-3.
- The mobility of charge carriers is 1.43 × 10^-3 m² V^-1 s^-1.
