Enter the email address you signed up with and we'll email you a reset link. The experiment was done for two types of semi-conductor crystals of Germanium (Ge) {3833 & 3911}, one having electrons as the majority charge carrier and other holes. The paper briefly describes the Hall effect and its application in semiconductor material analysis. If current is flowing through the crystal in the x Hall Effect Experiment. Finally, in October, 1879, Hall measured the lateral potential difference successfully. In this experiment you will measure the re-sistivity and the Hall coe cient as functions of the temperature, for an Al-doped germanium crystal. The whole system is mounted in a pen type case for further protection. The Hall E ect 1 Introduction In 1879, E. H. Hall observed that when a current-carrying conductor is placed in a transverse magnetic eld, the Lorentz force on the moving charges produces a potential di erence perpendic-ular to both the magnetic eld and the electric current. 2. These steps are completely independent of the type of sample and quantitized to values h/e2m, where m is an integer. The latter technique utilizing the Hall effect has the advantage of requiring only a very small probe and very simple instrumentation. It is the name given to the production of a voltage difference (Hall voltage) within an electrical conductor through the effect of an applied magnetic field.
