Fast spectroscopic signatures accelerated by deep learning

Often, simulations of spectroscopic measurements such as FTIR and Raman are used to assist experimentalists to characterize samples grown in their laboratories. Although this technique works (and is widely used), there can be a high computational cost associated with the spectral simulation. This project will utilize deep neural networks to develop an efficient and accurate methodology for simulating accurate spectroscopic signatures at significantly lowered computation cost than currently possible. This study will focus on 2D materials, beginning with graphene. Collaborator University of Montréal will provide expertise in computational materials, electronic structure and first principles simulations of nanoscale structure and spectra. The NRC will provide expertise on application of AI and deep learning to problems in nanoscience.
