Optical Absorption Modeling of Arbitrary Shaped Nanoparticles

Mullin P., Kozlowski G., Kozlowski P.G., Kozlowski G., Kozlowski P.G., Busbee J.D., Jones J.G., Wright State University, US

A method for modeling the optical absorption spectra of nanosize metal particles is demonstrated. Computer software has been developed to generate the absorption spectra from the particles geometry and material properties. The software breaks the [...]

Residual Stress Characterization in MEMS Microbridges using Micro-Raman Spectroscopy

Starman_Jr. L.A., Ochoa E.M., Lott J.A., Amer M.S., Cowan W.D., Busbee J.D., Air Force Institute of Technology, US

We characterize and measure the pre-released residual stress levels in polysilicon Micro-Electro-Mechanical Systems (MEMS) microbridges using micro-Raman spectroscopy. Raman spectroscopy is nondestructive, fast, and provides the potential for in situ stress monitoring during fabrication. Residual [...]
