In a Hall Effect experiment, a voltage is measured perpendicular to both the current flow and the magnetic field. What is the physical origin of this "Hall Voltage," and what two crucial properties of a semiconductor material can be determined by measuring it? Answer : The physical origin of the Hall Voltage is the **Lorentz force** acting on charge carriers as they move through a magnetic field. This simple experiment is profoundly important because it ... **carrier concentration `n`**, a fundamental parameter that dictates the material's electrical properties....
