Nanoscale Thermal Transport by Time-Domain Thermoreflectance (TDTR)

Measurement of thermal conductivity and interface conductance using picosecond pump-probe metrology.

Microscale Thermal Properties by Displacement Thermo-Optic Phase Spectroscopy (D-TOPS)

Simultaneous determination of thermal conductivity and the coefficient of thermal expansion (CTE) in small specimens and layers as thin as 1 µm.

Liquid Thermal Conductivity by I-TOPS

Immersion thermo-optic phase spectrocopy (I-TOPS) enables the measurement of extremely small volumes.

Thermal Boundary Resistance (TBR)

Non-destructive measurement of thermal boundary resistance in wafer-bonded interfaces and 3D integrated circuit die assemblies with probing depths up to 100 µm.

Materials Analysis & Characterization

Supporting characterization including picosecond acoustics, Rutherford backscattering spectrometry, X-ray reflectivity, and spectroscopic ellipsometry.
