WebThe Hall effect measurement for Zn-Te deposits of varying composition and thickness at room temperature by the conventional d.c. method. The electric and magnetic fields varied between 1 to 50 µA and 3.0 to 9.5 K Gauss respectively. The Hall voltage was found to be independent of electric and magnetic fields, the Hall coefficient (R H) WebHall mobility is highly dependent on sample temperature, so it's often desirable to monitor this temperature, particularly if the application involves repeating measurements each time the sample’s temperature is adjusted. Many test configurations include a temperature-measuring probe; for high accuracy work, the probe’s resolution should be ...

WebA Hall effect measurement system is useful for determining various material parameters, but the primary one is the Hall voltage (V H). Carrier mobility, carrier concentration (n), Hall coefficient (R H), resistivity, magnetoresistance (R B), and the carrier conductivity type (N or P) are all derived from Hall voltage. WebThe Hall mobility, nn, is obtained by measuring the deflection of electrons by a magnetic field while they are drifting in an electric field. Since the deflection occurs only while the electrons are quasi-free, nn is a measure of qf. Measurements of nu that have been done are for liquids of high drift mobility.
