Magnetic Hall Effect System, Hall Effect Measurement System
Semiconductor materials: SiGe, SiC, InAs, InGaAs, InP, AlGaAs, HgCdTe and ferrite materials etc.
Low impedance material: metal, transparent oxide, weak magnetic semiconductor materials, TMR material, ect.
High impedance material: Semi-insulating GaAs, GaN, CdTe, etc.
Hall-effect system components:
This system is consisted of electromagnet, high-precision electromagnet power supply, high-precision constant current source, high-precision voltage meter, gauss meter, connecting cables, standard sample, sample mount and the system software. The system contains specially developed DX-320 constant current source, six semi-microvolt meter and complex switching relays for Hall measurements (Integrally assembled switch). These have greatly simplified the connection and operation of experimental. DX-320 can be used alone as a constant current source or micro-volt meter. The system can be used to measure the carrier concentration, mobility, resistivity, Hall coefficient, and other important parameters of semiconductor material. These parameters must be known in advance to understand the electrical properties of semiconductor materials, so Hall Effect measurement system is an essential tool to understand and study of semiconductor devices and electrical properties of semiconductor materials. The results can be calculated by the software automatically, at the same time, it will get Bulk Carrier Concentration, Sheet Carrier Concentration, Mobility, Resistivity, Hall Coefficient, Magneto resistance, I-V curve and I-R curve measurement parameters. hall effect measurement system
