ThermoFisher Nexsa G2 is the next generation X-ray Photoelectron Spectrometer (XPS) that gives quantitative elemental composition and chemical state information about the sample surface (top 3 – 10 nm). Additional tools allow to perform ion etching, depth profiling, UPS, Raman, and ISS spectroscopies. The system contains:
Capabilities
- ✓Al Kα monochromated, focused X-ray source with variable spot size (10 – 400 µm)
- ✓Ar+ ion gun with ion energy range of 0.3 – 4 keV and monoatomic/cluster modes
- ✓Ultraviolet Photoelectron Spectroscopy (UPS) with He I/He II UV light source
- ✓Raman spectroscopy with a 532 nm laser
- ✓Ion Scattering Spectroscopy (ISS) with He ion source
- ✓Dual electron/ion flood gun for charge compensation
- ✓Sample holders include: vacuum transfer module, heating stage, SEM integration unit
