Surface Analysis Laboratory

Surface Analysis

Surface analysis involves the determination of the chemical distribution and structural composition of the outermost layers of solid surfaces using X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy (UPS), and time of flight secondary ion mass spectrometry (TOF-SIMS). Generally surface analysis means performing a chemical analysis in the first 5-10 atomic layers of the solid surface. Surface analytical techniques are also capable of measuring variations in composition with depth. Contact Dr Bill Gong ( or Outi Mustonen ( for information on surface analysis.

Examples of applications of surface analysis:

  • Surface treatments - surface modification of wool fibre
  • Film technology - breakdown and depth profiles of protective films
  • Metallurgy - stress corrosion cracking
  • Adhesives - quality control of production processes
  • Industrial catalysis - identification of catalyst poisons
  • Paints and coatings - thickness and composition
  • Microelectronics - impurity and dopant studies
  • Biomaterials - surface roughness
  • Mining - mineral composition and surface treatments
  • Polymers - chemical state of surface bonds
