The following are some of the frequently asked questions for Viva of the Four Probe Experiment, to determine the resistivity and Energy Band gap of a semiconductor. A.When a current carrying conductor is placed in a magnetic field mutually perpendicular to the direction of current a potential difference is developed at right angle to both the magnetic and electric field.This phenomenon is called Hall effect. What is the effect of temperature on Hall coefficient of a lightly doped semiconductor? Now one can define the current which in this case is flowing along the X-axis. Finally, in October, 1879, Hall measured the lateral potential difference successfully. 9.

The difference is that electrons in the upper bound of the valence band have opposite group velocity and wave vector direction when moving, which can be effectively treated as if positively charged particles (holes) moved in the opposite direction to that of the electrons.

The Hall Eï¬ect 1 Background In this experiment, the Hall Eï¬ect will be used to study some of the physics of charge transport in metal and semiconductor samples. A potential difference of 10 volts is applied across the edges. Some concepts should be very clear before the performance of the experiment, like knowledge of Flemming’s left-hand rule, Lorentz’s force and direction of the magnetic field. Hall effect is important and to explain it the direction of the magnetic force plays the role. https://apniphysics.com/how-to-observe-hall-voltage-in-the-physics-lab-by-using-hall-effect-experiment/.
