How we support your materials research

From wafer-scale metrology to AI-assisted analysis, each capability is built on instrumentation-grade rigor, and delivered with data you can defend in a review or a fab meeting.

Advanced Characterization

Optical metrology for thin films, layered structures, and their electronic and vibrational properties. We determine thickness, optical constants, bandgap, and vibrational signatures across your sample, non-destructively, with uncertainty stated rather than implied.

Surface and Defect Analysis

Structural, compositional, and defect-level analysis using X-ray and direct surface techniques, run standalone or alongside ellipsometry on the same sample so the datasets corroborate each other.

Scientific Consulting

Measurement is only useful if it answers the right question. We work with your team on the framing as well as the data: which technique actually resolves the ambiguity, how many samples you need, and what the result will and will not tell you.

AI & Data Analytics

Characterization campaigns generate more data than anyone reads. We build the tooling that turns spectra, maps, and image stacks into decisions, and hand it over as code you own rather than a black box.

Typical engagement

Not sure which technique fits? Describe the sample and we will recommend an approach.

Choosing a Technique

What each method is best at

A starting point, not a rulebook. Most real questions are answered best by combining two of these.

TechniqueAnswersBest suited to
Spectroscopic EllipsometryThickness, refractive index, extinction coefficientThin films and multilayer stacks on reflective substrates
Imaging EllipsometrySpatial variation of the abovePatterned, graded, or visibly non-uniform samples
ReflectometryThickness and interface quality, single measurementFast process checks on production-relevant samples
Photoluminescence (PL)Bandgap, defect states, carrier lifetimeSemiconductor and optoelectronic materials
Raman SpectroscopyPhase, strain, stoichiometry, layer count2D materials, carbon systems, phase-ambiguous films
Optical SpectroscopyTransmission, reflection, absorption, band edgeTransparent films, coatings, PV and display materials
X-Ray Diffraction (XRD)Phase, crystallinity, strain, textureCrystalline films, epitaxy, and polycrystalline coatings
X-Ray Fluorescence (XRF)Elemental composition and film thicknessMultilayer or coated samples needing composition data
X-Ray Photoelectron Spectroscopy (XPS)Surface chemistry, oxidation states, depth profilesInterfaces, contamination, and near-surface chemistry
Atomic Force MicroscopyTopography, roughness, step heightNanoscale surface questions and interface quality
Defect MetrologyDefect detection, classification, root-cause correlationYield-limiting defects on wafers and patterned samples
Optical ModelingDispersion models for new material systemsMaterials without established literature optical constants
