If current is flowing through the crystal in the x Better references for the purpose of our experiment are Azároff and Brophy, Electronic This part describes the Hall Effect apparatus, as well as the procedures for computer control and data collection. This effect is the famous Hall Effect. Make the Hall Effect Sensor board by fixing the Hall Effect sensor to the board. Abstract: In this experiment Hall’s Effect was studied/observed and various parameters like Hall’s coefficient, carrier density, mobility etc were measured/calculated. Alpha water-cooled magnet and power supply (Turn on water before turning on power supply. 4, with a magnetic field H in the z direction perpendicular to contacts 1, 2 and 3, 4. 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. Abstrak. Figure 1: Geometry of fields and sample in Hall effect experiment. 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. 2.1 Apparatus & Equipment List. The effect was discovered by E.H. Hall in 1879. 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. 2. Hall Effect Experiment. Figure 1: The Hall Effect Apparatus. 1.1 The simple theory of the Hall effect Consider a conducting slab as shown in Fig. Finally, in October, 1879, Hall measured the lateral potential difference successfully. 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. 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. In conclusion, the Hall effect was verified. At this time, Hall used thin gold foil to accomplish the experiment. Experiment handout for Hall effect, Physics 616, The Ohio State University. 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. 1. 2 the diagram of Hall Effect (the carriers are positive charges) 2 . Notice that the neon in the tube is fluorescing (emitting light) due to the excitation of the electrical current supplied from the battery. Consider a simple crystal mounted as in the Fig. 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. Figure 2: Hall Probe Detail Equipment. 166-167. After fixing the Hall Effect sensor, mark the board with scaled numeric values with the help of marker and scale. therefore, he suggested that Hall repeated the experiment. Fig. 1 with length L in the x direction, width w in the y direction and thickness t in the z direction. from Hall Effect measurements, which are a basic tool for the determination of mobilities. 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.
