Doctoral Researcher in Organic Substrates for Power Conversion Systems

This PhD project addresses critical thermal management challenges in power electronics by developing organic matrix composites as replacements for traditional ceramic substrates. The research focuses on synthesizing thermally conductive (nano)fillers with insulating coatings, optimizing their dispersion in polymer resins, and studying charge/matrix interfaces to minimize phonon scattering. The candidate will explore sol-gel methods for coating synthesis and evaluate magnetic nanoparticle grafting to enhance thermal performance. The work targets materials with thermal conductivity >3 W/m·K, dielectric strength ~3 kV/mm, and thermal expansion matching copper to prevent delamination during device cycling. Applications include electric motors, power modules, and renewable energy systems.
