Product introduction
The DX-50 Hall Effect System is a lab-grade solution designed for precise characterization of semiconductor materials. Built with a variable electromagnet and a dedicated DX-320 sourcemeter, it enables fast, accurate measurement of carrier concentration, mobility, resistivity, Hall coefficient, and more. Its automated software simplifies testing and data export, making it ideal for universities, R&D centers, and semiconductor labs. Compatible with materials such as graphene, InP, GaN, and SiC, this system supports both low and high-resistance samples. Designed for long-term use and reliability, it meets the demanding needs of advanced material research.
The DX-50 Hall Effect Testing System is suitable for studying the electrical properties of semiconductor devices and semiconductor materials. Experimental results are automatically calculated by the software, allowing simultaneous determination of parameters such as bulk carrier concentration, surface carrier concentration, mobility, resistivity, Hall coefficient, magneto-resistance, and more.
The Hall effect system consists of an electromagnet, high-precision power supply, connecting cables, high-precision constant current source, high-precision voltmeter, gaussmeter, standard samples, sample mounting bracket, and system software.
The DX-320 effect meter specially developed for this instrument system assembles a constant current source and a switch (a six-and-a-half microvoltmeter and a Hall-complex switching relay) into one. Greatly reduced the connection and operation of the experiment. The DX-320 can be used alone as a constant stream and a microvolt.
