Nanomaterials under extreme conditions

Abstract

Studying materials under pressure allows for studying their thermodynamic properties, their mechanical properties and electromechanical coupling, among others.

In this talk, I will review our works on high-pressure studies of oxide nanoparticle that led us to propose a thermodynamic model through their pressure-induced transitions: effect of interface, of disorder, of synthesis path. In particular, I will discuss the case of ZnO nanoparticles.

In a second part, I will discuss results we obtained on graphene at high pressure. More specifically, I will discuss how the pressure is transferred from the substrate to the single layer.

Finally, I will present recent works that aimed to determine the deformation potentials of InP nanowires in the wurtzite crystallographic phase.
