What is the difference between hall-effect in metals and semiconductor?

because we have hall cofficient =1/ne. where the n=no of electron ,e=charge of electron. we know that "n "in metal is very large. so that R=HALL COFFICIENT" is very small FOR it .so we can not find sufficient result for hall cofficient so we use semi conductor which gives non zero hall cofficient.

What is the difference between ac Hall effect and dc Hall effect?

The AC Hall effect is used to measure the sign and magnitude of an alternating magnetic field, whereas the DC Hall effect is used to measure the sign and magnitude of a steady magnetic field. In AC Hall effect, the magnetic field changes direction periodically, while in DC Hall effect, the magnetic field is constant.

How can you find more information about the Hall effect?

The Hall effect was discovered by Edwin Hall, and references the difference in electrical current when exposed to a magnetic field. One can find out more about the Hall effect by consulting a physics textbook or physics teacher or professor.


What is hall effect hall voltage?

The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879


Why intrinsic semiconductor has negative halls coefficient?
