"Mastering supramolecular interactions to free electrons and generate hybrid van der Waals heterostructures" by Emanuele Orgiu

Mastering supramolecular interactions to free electrons and generate hybrid van der Waals heterostructures
by Emanuele Orgiu, University of Quebec (UQ) – Institut national de la recherche scientifique (INRS), Centre Énergie Matériaux et Télécommunications

Abstract:
In this seminar I will talk about the importance of controlling supramolecular interactions and mainly focus on two cases.

First, I will describe how a subtle change in chemical structure can give rise to a profoundly different delocalization of electrons in organic single crystals. To unravel the different electron-phonon behavior in such crystals as a function of the molecular structure, we employed a plethora of experimental and computational techniques to identify killer molecular displacements responsible for the electron localization.

As well, I will discuss the role of superimposed 2D molecular supramolecular lattices over Quantum Materials in generating novel hybrid van der Waals heterostructures. I will provide some examples on charge- and magneto-transport in such structures.
