Hall effect measurement system DX-30

concentricityresistivityfor semiconductors

DX-30 Permanent Magnet Hall Effect Meter consists of a permanent magnet, a high-precision constant current source high-precision voltmeter, a Hall effect sample holder, a standard sample, a high-precision Gauss meter and system software. DX-30 Permanent Magnet Hall Effect Meter Used to measure important parameters such as carrier concentration, mobility, resistivity, Hall coefficient and other important parameters. These parameters are necessary to understand the electrical properties of semiconductor materials, so the Hall effect test system is a necessary tool for understanding and studying the electrical properties of semiconductor devices and semiconductor materials. We can provide various Hall effect test systems for teaching and research; It is the largest manufacturer of high-precision Hall devices in China; Technical support: Institute of Semiconductors, Chinese Academy of Sciences (Hall effect research for 30 years). 1. Both ends are high-stability permanent magnets, and the magnetic field value is around 500mT (the specific value is subject to actual measurement); 2. The distance between the pole heads of the two permanent magnets is: 18mm, the pole diameter is: 48mm, and the pole surface diameter is: 33mm; 3. The permanent magnet is a nuclear magnetic resonance NMR series permanent magnet; it has good stability and a very uniform magnetic field, ensuring that the uniformity of the uniform area is 1~5*10-5; 4. Permanent magnets with relevant magnetic sizes can be customized according to customer needs to cooperate with Hall effect testing experiments.
