Hall Effect: It states that if a “specimen (meta or semiconductor) carrying the current I is placed in traverse magnetic field B, then Electric field Intensity E is induced in a direction perpendicular to both I and B”.
From Hall Experiment, we can determine the following properties:
- Whether the specimen is a metal or semiconductor. In the case of semiconductors, we can found whether it is intrinsic, N-type, or P-type.
- The carrier concentration in the sample.
- Mobility of charge carriers.
- Magnetic field intensity.
- Used in designing of Hall effect transducers.
- Hall voltage is induced in between the bottom and upper surfaces of the specimen.
- If the polarity of hall voltage is positive for the bottom surface, the given specimen is P-type.
From the above properties, we can say that, Option (b) is correct.
