Which of the following parameters can’t be found with Hall Effec...
The
Hall effect
is the production of a
voltage
difference (the
Hall voltage
) across an
electrical conductor
that is transverse to an
electric current
in the conductor and to an applied
magnetic field
perpendicular to the current.
It was discovered by
Edwin Hall
in 1879.
The Hall Effect is used for finding the whether the semiconductor is of n-type or p-type, mobility, conductivity and the carrier concentration.
Hence the correct answer is (D)
