Spectroscopy Measures Nanoscale Material Strain

Facebook Twitter LinkedIn Email Comments
A new spectroscopy technique could lead to microelectronics that perform better under stress and heat. A team from Purdue University developed the technique, called nanomechanical Raman spectroscopy. Raman spectroscopy can provide information about the chemical makeup of a material. “But we have not been able to incorporate in-situ stress or deformation into those chemical signatures,” said Dr. Vikas Tomar, an associate professor in Purdue’s School of Aeronautics and Astronautics. “Now we have combined nanomechanical measurements into Raman...Read full article
