Will hall voltage be identical in semiconductors and conductors?

No, the Hall voltage will not be identical in semiconductors and conductors due to differences in charge carrier concentration and mobility. In conductors, there are typically more free charge carriers, leading to a different Hall voltage response compared to semiconductors, which have fewer charge carriers and can also have both electrons and holes contributing to the Hall effect. Additionally, the type of charge carriers affects the sign and magnitude of the Hall voltage in these materials.
