Measurement of Hall coefficient enables the determination of:
Explanation:
The Hall effect is a phenomenon in which an electric field and a magnetic field are applied perpendicular to each other on a conductive material, which results in the development of an electric field in a direction perpendicular to both the applied fields. This effect is used to measure the Hall coefficient, which can be used to determine the type of conductivity and concentration of charge carriers in a material.
Type of conductivity:
The Hall coefficient can be used to determine whether a material is a conductor or a semiconductor by measuring the sign of the Hall voltage. If the sign is negative, it is an n-type semiconductor, and if it is positive, it is a p-type semiconductor.
Concentration of charge carriers:
The Hall coefficient can also be used to determine the concentration of charge carriers in a material. The Hall coefficient is given by the equation R_H = 1/(nq), where R_H is the Hall coefficient, n is the concentration of charge carriers, and q is the charge of a carrier. Therefore, by measuring the Hall coefficient, the concentration of charge carriers can be calculated.
Conclusion:
Thus, the measurement of Hall coefficient enables the determination of the type of conductivity and concentration of charge carriers in a material, which is useful in understanding the electrical properties of the material and designing electronic devices.
