Overview

Olivier Delaire's research program investigates atomistic transport processes of energy and charge, and thermodynamics in energy materials. The nanoscale studies probe atomic dynamics and elementary excitations in condensed-matter systems (phonons, electrons, spins), their couplings and their effects on macroscopic material properties. Current materials of interest include thermoelectrics, ferroelectrics/multiferroics, spin-caloritronics, and photovoltaics. The Delaire group develops new methods to reveal microscopic underpinnings of thermal transport, by integrating neutron and x-ray scattering measurements with quantum-mechanical computer simulations. This combined experimental and computational approach opens a new window to understand and control microscopic energy transport for the design of materials enabling novel technologies for energy applications (thermoelectrics, solid-state batteries, photovoltaics) and information storage and processing (multiferroics, metal-insulator transitions, topological materials). In addition to state-of-the-art scattering experiments and first-principles simulations, our team also uses transport measurements, optical spectroscopy, materials synthesis, calorimetry, and thermal characterization, with the goal of gaining deeper atomistic understanding for developing future materials.
