Cosme Milesi-Brault

Cosme Milesi-Brault is a Professor leading the Structures, Properties and Modeling of Solids laboratory. His research focuses on antiferroelectric materials, phase transitions, and solid-state physics. Key areas include exploring soft-mode-driven transitions in materials like francisite and barium zirconate, as well as exciton dynamics in perovskite systems. He has contributed to understanding polarization mechanisms in ferroelectric uniaxial tungsten bronze and phase-boundary phenomena in PbZrTiO3 systems.

• Explores applications of antiferroelectrics in optoelectronics and energy storage
• Develops novel thin film fabrication techniques for multiferroics
• Investigates structural dynamics using advanced spectroscopic methods

Research interests combine experimental characterization with computational modeling, addressing fundamental questions about material behavior at the atomic scale. Recent work highlights birefringence effects in polycrystalline films and leakage current mitigation in BiFeO3 thin films.
