The Hall Effect. 1 Background. In this experiment, the Hall Effect will be used to study some of the physics of charge transport in metal and semiconductor samples. In 1879 E. H. Hall observed that .. out the carrier density n from the overall conductivity formula for ?, and define a new quantity called the mobility µ: µ = ?. ?.
2.7.5. The Hall Effect. The Hall effect describes the behavior of the free carriers in a semiconductor when applying an electric as well as a magnetic field. The experimental setup shown in Figure 2.7.7, depicts a semiconductor bar with a rectangular cross section and length L. A voltage Vx is applied between the two contacts

Observation of the Hall Effect, and measurement of the Hall constant of a few semi-conductors and metals samples. II THEORETICAL BACKGROUND. When a current density j = I S floes through a sample (metal or semiconductor) that is immersed in a magnetic B field, perpendicular to the sample (Fig. 1), a Hall voltage VH
problem that this formula generalizes to a wide class of materials. Note also that the Hall field is large for low carrier concentrations: we might expect that the effect will be harder to detect in metals than in semi-conductors. The Hall field Ey can be measured by the voltage difference between points a and b (Fig. 3) since. hE.
Hall Coefficient RH . 1. Determine the type of majority charge carriers ( i.e. determine wether the semiconductor sample is of the n-type or p-type ). 2. Determine the charge carrier density ( or carrier concentration per unit volume ) in the semiconductor crystal. 3. Determine the Hall Angle H . The Hall effect has many

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 to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.
