Explanation:
Hall Coefficient Measurement:
- The Hall coefficient is a characteristic of a material that describes its response to an applied magnetic field perpendicular to the electric current flowing through it.
- It is defined as the ratio of the induced electric field to the product of the applied magnetic field, current density, and thickness of the material.
Determination of Type of Conductivity and Concentration of Charge Carriers:
- By measuring the Hall coefficient, one can determine whether the material is n-type (electrons are the majority charge carriers) or p-type (holes are the majority charge carriers).
- The sign of the Hall coefficient indicates the type of charge carriers.
- The magnitude of the Hall coefficient can be used to calculate the concentration of charge carriers in the material.
Conclusion:
- In conclusion, the measurement of the Hall coefficient enables the determination of the type of conductivity (n-type or p-type) and the concentration of charge carriers in a material.
