This effect is the famous Hall Effect. The effect was discovered by E.H. Hall in 1879. The above argument provides a simple picture in which to think about the Hall effect — and in fact leads to the correct answer if pursued. 1. Consider a simple crystal mounted as in the Fig. Hall Effect Experiment. Make the Hall Effect Sensor board by fixing the Hall Effect sensor to the board. Fig. 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. 166-167. 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. 2 . After fixing the Hall Effect sensor, mark the board with scaled numeric values with the help of marker and scale. Hall Effect Sensors consist basically of a thin piece of rectangular p-type semiconductor material such as gallium arsenide (GaAs), indium antimonide (InSb) or indium arsenide (InAs) passing a continuous current through itself. Experiment handout for Hall effect, Physics 616, The Ohio State University. therefore, he suggested that Hall repeated the experiment. 4, with a magnetic field H in the z direction perpendicular to contacts 1, 2 and 3, 4. Hall Effect experiment have been carried out with the objectives are: to determine relationship between Hall Current I H and voltage U H, to measure sensitivity of Hall element K H from GaAs semiconductor, and to determine magnetization curve of silicon steel with Hall element. Better references for the purpose of our experiment are Azároff and Brophy, Electronic At this time, Hall used thin gold foil to accomplish the experiment. If current is flowing through the crystal in the x The marking should be as 0 mm at null position, (where the head of the Hall Effect sensor is there) and with the intervals of 20 mm. As long as the magnetic field and the current stayed below some threshold, there was a linear relationship between the voltage measured, and the current and B field applied. Finally, in October, 1879, Hall measured the lateral potential difference successfully. Abstrak. 2. Figure 1: Geometry of fields and sample in Hall effect experiment. 1 with length L in the x direction, width w in the y direction and thickness t in the z direction. The theory of the Hall effect is discussed in Omar, Sections 4.10, 5.19, 6.8, Hutchison and Baird, the Physics of Engineering Solids, Section 11.6, and Kittel, Elementary Solid State Physics, pp. In conclusion, the Hall effect was verified. Figure 2: Hall Probe Detail Equipment. The ends of the Hall Effect Tube (a vacuum with a trace of neon gas) are connected to a Battery.A smaller tube intersects with the larger tube; attached to its ends are electrodes that are connected to a Voltmeter to detect voltage. Abstract: In this experiment Hall’s Effect was studied/observed and various parameters like Hall’s coefficient, carrier density, mobility etc were measured/calculated. This part describes the Hall Effect apparatus, as well as the procedures for computer control and data collection. Figure 1: The Hall Effect Apparatus. Alpha water-cooled magnet and power supply (Turn on water before turning on power supply. 1.1 The simple theory of the Hall effect Consider a conducting slab as shown in Fig. Notice that the neon in the tube is fluorescing (emitting light) due to the excitation of the electrical current supplied from the battery. from Hall Effect measurements, which are a basic tool for the determination of mobilities. 2 the diagram of Hall Effect (the carriers are positive charges) 2.1 Apparatus & Equipment List.
