Electronic Measurement, Lakeshore 7507 - Status: Available
|
The Lakeshore Hall Measurement System capabilities include Hall coefficient, Hall voltage, resistance, resistivity, magnetoresistance, I-V curves, carrier concentration and mobility. The HMS measures most compound semiconductor materials including pHEMTS, SiGe, SiC, InAs, InGaAs, InP, AlGaAs, HgCdTe, and ferrites; low resistance materials including metals, transparent oxides, dilute magnetic semiconductors, and TMR materials; and high resistance materials including semi-insulating GaAs and GaN, CdTe, and photodetectors. Quantitative Mobility Spectrum Analysis (QMSA) software technique analyzes variable magnetic field Hall data to resolve individual carrier mobilities and densities in multi-carrier devices. The QMSA software’s reliability and sensitivity make it the ideal technique for routine characterization of various multi-carrier materials and high mobility heterostructure devices.
