Modelling Raman spatial imaging with deep learning

FY 2022-23 · 2022-11-30

Summary
This project proposes to develop the capability to simulate the vibrational properties of 100k atom size systems using deep neural networks (DNN) methods. Such simulations will advance the ability to directly compute what is currently measured with novel Raman techniques. In this project, theoretical and experimental groups will collaborate to bring simulation tools to the next level, where generated data can be directly compared to experimental Raman spectra of complex matter. This testing platform will consist of Raman imaging of defective graphene sheets, systems that cannot be addressed with standard numerical methods because of the size of the problem. The goal is to develop AI-assisted tools to understand better the type of defects that cause a certain Raman response. These tools will use density-functional theory (DFT) simulations as input to guarantee the accuracy and predictability of the approach. These tools will help in the analysis of 2D materials. One possible use of 2D materials is in gas detection and having a better understanding of Raman signals on these surfaces before and after being exposed to certain gases will provide a guide on which materials have the better potential for this type of application.

Description (French)
Au terme de ce projet, on pourra simuler les propriétés vibratoires des systèmes de la taille de 100 000 atomes grâce aux méthodes des réseaux de neurones profonds (RNP). Les simulations de ce genre permettront de calculer directement ce que mesurent présentement les nouvelles techniques Raman avec plus de facilité. Les équipes responsables de l’aspect théorique du projet et de l’expérimentation collaboreront afin de faire progresser les outils de simulation au niveau suivant, c’est-à-dire celui où les données seront comparées directement au spectre Raman des expériences sur les matériaux complexes. Le banc d’essai consistera en un système d’imagerie Raman pour les feuilles de graphène défectueuses impossibles à analyser avec les méthodes numériques courantes en raison de l’ampleur du problème. On espère mettre au point des outils assistés par intelligence artificielle qui aideront à mieux comprendre la nature des défectuosités à l’origine de telle ou telle réponse Raman. Ces outils recourront aux simulations de la théorie de la fonctionnelle de la densité (DFT) pour garantir l’exactitude et la prévisibilité de l’approche retenue. Ils faciliteront l’analyse des matériaux bidimensionnels, dont on pourrait se servir pour détecter les gaz. Mieux comprendre les signaux Raman émis par ces surfaces lorsqu’elles sont exposées à certains gaz nous guidera sur le choix des matériaux qui conviennent le mieux aux applications de cette nature.
