Amaury Baret

PhD candidate & teaching assistant in materials physics,
Department of Physics, University of Liège.

I study transport and percolation in stochastic media, and the optical response of the same disordered systems through numerical modelling: Mie scattering and transfer-matrix methods. The central object of my PhD is the silver nanowire network: a disordered transparent conductor on which I build theory, simulation, and experiment in parallel, with applications to energy materials, including smart windows and low-emissivity coatingss.

Stochastic media & computational physics.

Hover any side to read the specific threads of my research programme — the physics, the experimental techniques, and the computational methods that support them.

§ Research in 60 seconds

My PhD sits at the intersection of three tightly coupled threads. The physics is the transport, percolation, and optical response of disordered metallic nanowire networks, and their integration with VO₂ and other oxide layers for smart-window, low-emissivity, and radiative-cooling applications. The experimental side covers fabrication and characterisation: RF magnetron sputtering, spray- and spin-coating, SEM and XRD, and UV–Vis–NIR spectrophotometry for emissivity and optical-constants extraction. The computational side builds the interpretive layer: percolation and graph-theory models of electrical connectivity, Mie and transfer-matrix optical modelling, and HPC simulation on SLURM-scheduled clusters (MPI / OpenMP, COMSOL, custom C++/Python solvers). Theory, simulation, and experiment advance in parallel.
