Hall effect experiment lab report

For our sample w = mm l = mm d = 0. B = ______ Gauss = ______ x10-Tesla. After we have determined the carrier concentration and type from Equations (7) and (9), we can use some further experimental information to determine the carrier mobility. Abstract In order to investigate the nature of charge carriers in electric conductors, we carry out an experiment to measure the Hall coefficients of silver and tungsten.

An experimental report by Harsh Purwar and group from Indian Institute of Science Education and Research, Kolkata.

After successfully completing this laboratory workshop, including the assigned reading, the lab problems, and any required reports , the students will be able to: 1.

Determine the semiconductor type from the polarity of the Hall voltage, knowing the orientation of all fields and currents in the experimental .

By con- trolling external parameters, such as pressure, magnetic field and discharge current, we will measure the Hall Voltage and . The voltage developed across the conductor is called Hall voltage. Better references for the purpose of our experiment are Azároff and Brophy, Electronic. I for constant magnetic field and determine RH using the . In this experiment , the Hall Effect will be used to study some of the physics of charge transport in metal and semiconductor samples. Hall effect has been one of the principal motivators leading to a. Hall Probe, Indium Arsenide (InAs), red and black current leads, green and white Hall voltage leads, installed in . Department of Mechanical and Environmental Engineering.

University of California, Santa Barbara. The Hall coefficient obtained may be used to determine t. Sc Physics IIT Kharagpur, A Physics teacher and Science Activist. The object of this experiment is to study various properties of n- and p-doped germanium crystals. Experiment by students of IIT Patna.

The temperature dependence of the electrical conductivity, and the Hall Effect in germanium, will be demonstrated. The sign of the charge carriers responsible for conduction, the charge carrier concentration, . I decided it would be interesting to cover the hall effect. Edwin Hall did over at Johns Hopkins back in the day. I use for after effects is still not working prop. This video shows the procedure to measure: 1) Hall Coefficient 2) Charge Density 3) Charge Mobility as per stated in your book.

Hall Effect in Electronics is explained with n-type semiconductor and p-type semiconductor in this video along with few applications of Hall Effect. The experimental set-up is shown in Fig. The plate must be brought up to the magnet very carefully, so.
