Measuring the Hall coefficient necessitates a deft calculation. One must gauge the Hall voltage for a given magnetic field, coupled with the strength of the electric current, and the thickness of the semiconductor. The formula dances as follows:

\[V_{H} = \frac{R_{H} ⋅ I ⋅ B}{d}\]

Or, should you desire the Hall coefficient directly:

\[R_{H} = \frac{V_{H} ⋅ d}{I ⋅ B}\]

The story, however, unfolds with an added layer of intrigue. Depending on the type of semiconductor (p-type or n-type), a Hall voltage of either positive or negative temperament is bestowed upon us. And if one charge carrier type reigns supreme in the transportation process, one can delve even deeper. By employing an elegant formula, the charge carrier density ‘n’ and mobility ‘m’ of the sample can be unraveled:

\[n = \frac{1 }{R_{H} ⋅ e}\]

\[μ = \frac{R_{H}}{ρ}\]

Where ‘e’ stands as the charge of the charge carrier, and ‘ρ’ represents the specific resistance of the material.
