My research activities are concerned with unravelling the electronic properties of semiconductors and organic materials used for device applications for the conversion and storage of solar energy. I I use electron paramagentic (spin) resonance (EPR, ESR) techniques or synchrotron-based characzerization to identify nanoscopic processes that limit device efficiency.

The main methods that we use for EPR studies are

    • Continuous-wave electron spin resonance (cw ESR) and time-domain ESR in a frequency range from MHz to THz
    • Electrically and optically detected magnetic resonance (EDMR and ODMR) detection in both continuous-wave and time-domain
