Applied Physics (PA)

Coordinator : Benoit JOUAULT

⚛️ The Applied Physics Division conducts research focused on applications while maintaining a close connection with studies of fundamental physics.

The research activities are organized around three complementary themes:

🧩 Innovative Materials: From Growth to Physics

This theme focuses on the growth and characterization of advanced materials — graphene, CIGS, wide-bandgap semiconductors, hybrid organic–inorganic materials, oxide glasses, and ultra-porous materials — with the dual aim of understanding their fundamental properties and developing new devices.

🌱 Physics for the Environment and Health

This theme brings together research addressing environmental and health-related challenges, including:

  • solar energy conversion and pollutant detection
  • development of instruments for agroecology
  • bioactive glasses for bone repair
  • design of micro- and optofluidic devices for chemical and biomolecular analysis

⚡ Quantum Transport and Terahertz Spectroscopy

This theme explores quantum transport phenomena and the optical properties of topological and Dirac materials, with the following objectives:

  • investigation of the quantum Hall effect and its extensions (quantum capacitance and quantum inertia)
  • understanding of topological phases and the quantum spin Hall effect
  • study of cyclotron emission and strong light–matter coupling in Dirac materials
  • exploration of low-energy excitations in two-dimensional materials
