Abstract: So far，it has been still necessary for obtaining the types of electrical conductivity in semiconductor

materials and many parameters obtained to use Hall effect experiment. So，Hall effect experiment is a very

important classical experiment. However，at the same time as Hall effect happens，there are a lot of side effects.

The measured value of Hall effect voltage always deviates from its real value. It results in a certain deviation of

measured parameters. In practice，the symmetrical measurement is often used to eliminate the influence of side

effects. However，there is symmetry breaking in the data columns which are measured by the symmetric measurement.

Considered the carrier's motion，the origin of symmetry breaking is gradually analyzed which is the joint action

of an electric field and a magnetic field. And magnetic field is stronger than electric field in symmetry breaking.

So that semiconductor material properties is studied.

Key words: Hall effect, symmetric measurement, symmetry breakage
