Hall effect is useful for the measurement of a semiconductor’sa)...
Hall Effect is basically the production of voltage (known as hall voltage) across conductor transverse to an electric current and to an applied magnetic field perpendicular to the current.
Application of Hall Effect:
  • To determine the type of semiconductor
  • To calculate the carrier concentration
  • To determine mobility (hall mobility)
  • To Measure magnetic flux density
From Hall Effect we have:

Where the hall coefficient is given as:

Hall Effect can be used to measure the carrier concentration and type of semiconductor.
