We are an experimental group of chemists, physicists and engineers that investigates the structure-function relationship in functional materials such as semiconductors, ionic-conductors and ferroelectrics. Specifically, we are interested in phenomena that stems from strongly anharmonic atomic displacements.

 

Most modern theories that explain and predict macroscopic properties of functional materials relay on the harmonic approximation. The essence of this approximation is the assumption that the vibration of atoms around their equilibrium position is harmonic. In reality, all atomic vibrations are anharmonic and this anharmonicity can lead to strong changes in a material’s observed conductance, thermal expansion or absorption and emission spectra.

We investigate the properties of functional in materials that exhibit strongly anharmonic atomic motion and are therefore not well understood or controlled.
