Surface Analysis
Instrument Capabilities
The Kratos XPS system is a multi-technique surface analysis platform that combines photoelectron and ion spectroscopies with surface-mapping capabilities. It is primarily used to determine the elemental composition and chemical state of material surfaces, providing detailed information about surface chemistry and electronic structure.
Available Techniques:
- X-ray Photoelectron Spectroscopy (XPS): Provides information on the elemental composition, chemical states, and chemical bonding of materials.
- Ultraviolet Photoelectron Spectroscopy (UPS): Provides information on valence-band electronic structure and work function measurements.
- Low-Energy Ion Scattering Spectroscopy (ISS): Provides information on the elemental composition and near-surface structure of solid surfaces.
Key features
- Detected signal: Photoelectrons emitted from atoms within the near-surface region
- Elemental range: Elements from lithium (Li) to heavy metals
- Detection limits: Approximately 0.1–1 atomic %
- Depth resolution: Approximately 2–8 nm
- Depth profiling: Approximately 0.5 nm/s using an argon-ion beam
- Lateral resolution: Approximately 15–500 µm.
Fees and Policies
- UT Users: $20/hour
- Higher Education/State Agencies: $91/hour
- Corporate/External Users: $91/hour
