hall effect experiment lab report

Briefly explain the difference between p-type and n … In the presence of a magnetic field B 0 along the z-direction, the holes will experience a force (the Lorentz force) driving them towards the bottom of the sample as shown in Figure 1. Notice that the neon in the tube is fluorescing (emitting light) due to the excitation of the electrical current supplied from the battery. If you find papers matching your topic, you may use them only as an example of work. Student Manual: This experiment introduces students to the Hall Effect which is a fundamental principle of magnetic field sensing. This principle can be regarded as an extension to Lorentz Force which is the force acting on the charge carriers (Electrons and Holes) passing through a magnetic field. These lines should pass through the origin, while fitting the data pretty well. with units of m 3 /C. Briefly explain the difference between metals and semiconductors. Note that there is NO eating or drinking in the 111-Lab anywhere, except in rooms 282 & 286 LeConte on the ... All pages in this lab I. The electric potential difierence between the two sides of the conductor is known as the Hall volt-age VH. Hall Effect in Semiconductor II. 10 Report Last day of the experiment please fill out the Experiment Evaluation [1] 11 References Hall Effect in a Semiconductor Description (SHE) 1. Hall Effect Consider the sample of p-type semiconductor with current density J x flowing in the x-direction. OBJECTIVE The conductivity, σ, of a silicon sample at room temperature will be determined using the van der Pauw method. The aims of this laboratory work are to study experimentally the classical Hall effect, linear dependence of Hall voltage on the current intensity through the plate, and to determine, within the potential difference produced by the Hall effect. Lab report guidelines: Your lab reports should address all of the following (and may, of course, include additional information and analysis): Explain the Hall effect in words. b) Hall effect for positive charge carriers v d v d Figure 1: Hall efiect fleld. The Leybold setup minimizes this effect by attaching one wire to one side, and two to the other side of the sample in such a way that the latter two wires lie on either side of the equipotential surface to which the first is attached, exactly as in research-lab measurements. the potential difference produced by the Hall effect. CONDUCTIVITY AND THE HALL EFFECT 1. The Hall Effect voltage, V H, and Hall coefficient, R H, for the same sample will be measured using a magnetic field. Note that d is the dimension of the probe, which was measured parallel to the applied magnetic field during the experiment.. The latter technique utilizing the Hall effect has the advantage of requiring only a very small probe and very simple instrumentation. If the width of the conductor is d, the rela-tionship between the electrostatic fleld and the Hall … Prepare a table that includes the following information, which refers to the six curves plotted in part (2B). During this laboratory, you will use a Hall probe to study the magnetic field distributions produced by both a Helmholtz coil and a solenoid. LAB III. The physical mechanism of the Hall effect is discussed in Appendix I. These measurements will enable the student to determine: the Hall Effect Principle explains the behavior of charge carriers when it is exposed to electricity and magnetic fields. Students will measure Hall coefficient and carrier charge concentration in a given semiconductor crystal which will help them to understand important … 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.
