The Hall Effect. Note: Please read the Radiation Safety Regulations at the back of this book. Objectives of the Experiment. The behaviour of the Hall voltage in a sample of doped germanium is studied in three different set-ups as follows: 1. 2. Constant magnetic field and temperature and varying control current.
The Hall effect has provided us with a peculiarly revealing insight into Maxwellian theory during the years in which it was most actively pursued.
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 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. This e ect is known as the Hall e ect [1].
7 lip 2021 · The observation of the quantum anomalous Hall (QAH) effect in thin films of chromium-doped (Bi,Sb)2Te3, a magnetic topological insulator shows a plateau in the Hall resistance as a function of the gating voltage without any applied magnetic fields, signifying the achievement of the QAH state.
Introduction. In 1879, E. H. Hall observed that when a current-carrying conductor is placed in a transverse magnetic field, the Lorentz force on the moving charges produces a potential diference perpendicular to both the magnetic field and the electric current.
The Hall Effect can be used to illustrate the effect of a magnetic field on a moving charge to investigate various phenomena of electric currents in conductors and especially semi-conductors.
