Diagnosis of Tooth Decay Using Polarized Micro-raman Confocal Spectroscopy

The tooth enamel presents a Raman spectrum with strong polarization anisotropy. Carious lesions of the enamel will produce an alteration of local symmetry. This will reduce the anisotropy of the Raman spectra. Thus micro-Raman polarized spectroscopy could be a used in early detection of teeth caries.

3D Temperature Measurement in IC Chips using Confocal Raman Spectroscopy

We have demonstrated the feasibility of depth and surface temperature measurements in active areas of semiconductor devices using confocal Raman spectroscopy. Using micro heaters, we created a 3D temperature profile across micron size volume. We determined the temperature profile with sub-micron resolution and obtained good agreement with calculations. Theoretical uncertainty in temperature det...

Depth-resolved confocal micro-Raman spectroscopy for characterizing GaN-based light emitting diode structures.

In this work, we demonstrate that depth-resolved confocal micro-Raman spectroscopy can be used to characterize the active layer of GaN-based LEDs. By taking the depth compression effect due to refraction index mismatch into account, the axial profiles of Raman peak intensities from the GaN capping layer toward the sapphire substrate can correctly match the LED structural dimension and allow the...
