Raman Spectroscopy

Understanding the Relationship Between Localized Mechanical Properties and Material Structure

Raman Spectroscopy is a powerful technique for spatially-resolved characterization of the chemical composition and structure of materials. Combined with nanoindentation, a greater understanding of structure-mechanical relationships can be achieved. Spatial correlation of nanoindentation and Raman characterization provides a direct correlation between nanomechanical properties and localized chemical makeup, crystallinity, polymorphism, phase, and intrinsic stress/strain. Additionally, automated Raman analysis before and after nanoindentation enables rapid investigation of residual structural changes within the material resulting from the deformation process. The coupling of in-situ Raman spectroscopy with nanoindentation and Bruker's other Hysitron nanomechanical testing techniques opens new areas of research by providing greater insights into mechanical properties and deformation behavior at the nanoscale and microscale.

Bruker has developed a fully-integrated Raman system for the Hysitron TI 980 TriboIndenter and Hysitron TI 950 TriboIndenter nanomechanical test instruments. Patented electrostatic transducer technology enables industry-leading sensitivity and reliability for nanoscale mechanical characterization, while a high-precision encoded staging system automates the testing process and provides exceptional spatial resolution between Raman and nanomechanical results. Researchers can define the characteristics of the integrated laser source and spectrometer to meet individual research needs.
