Strong Exciton Regulation of Raman Scattering

What Has Been Achieved

A new highly efficient method to calculate resonant Raman intensities including excitonic effects.    

Importance of Achievement

This new method allows us to better interpret and utilize high-throughput optical characterization of 2D materials, including potential roles of defects and heterostructures. This could be enabling of data-intensive modes of analysis and allows us to access new routes towards understanding electron-phonon interactions.  

Unique Features of the MIP That Enabled Project

The 2DCC-MIP mission of pushing the state-of-the-art in advanced characterization of 2D materials.
