Characterization and Chemical Analysis
|
Skilled technicians and scientists, using a range of methods and equipment, will ensure that the properties of silicon ingots and wafers are well established. In our facilities, we offer the following equipment for analysis/characterization of silicon materials:
- Sinton Consulting WCT-100 - Life time of minority charge carriers by Quasi Steady State - Photo Conductance (QSSPC)
- Unit built for measurement of life times directly on unpassivated silicon blocks
- Jandel Scientific - 4-point electrical resistivity measurement
- PVScan 6000 - Unique equipment for advanced optical characterization of silicon wafers
- Mapping of dislocations, coarse in elusion and grain boundaries
- Light Beam Induced Current (LBIC) mapping of solar cell efficiency
- Reflectivity mapping
- Hitachi FEGSEM and FEGTEM (Field Emission Gun Scanning/Transmission Electron Microscopy) – High resolution electron microscopy
- Determination of crystal orientation in silicon grains
- Visualisation and analysis of defects and inclusions
- Thermo Element II GDMS (Glow Discharge Mass Spectroscopy) Elemental impurity analysis in solid samples
- For detection of trace element in Si and other materials
- Detection limit in the ppb range
