Hall Effect Analysis
L79/HCS-Hall Effect Measurement System
The L79/HCS System permits the characterization of semiconductor devices, it measures: mobility, resistivity, charge carrier concentration and Hall coefficient.
The roughed desktop setup offers different sample holders for various geometries and temperature requirements. An optional low temperature (LN2) attachments and a high temperature version up to 240°C ensure that all fields of application can be covered. Different permanent and electric magnets provide fixed or variable magnetic fields up to several tessla.
The comprehensive Windows based software provides I-V and I-R Plot.
The system can be used to characterize various materials including Si, SiGe, SiC, GaAs, InGaAs, InP, GaN (N Type & P Type can be measured), metal layers, oxides, etc.. Sample testing can be performed to demonstrate the system´s capability.
• Carrier concentration
• Alpha (horizontal/vertical ration of resistance)
• Hall Coefficient
