Who we are
We are a young and dynamic research group based in Bern, Switzerland, and led by Prof. Natalie Banerji. In our group, chemists as well as physicists and material scientists work side by side to understand and optimize electronic devices based on organic electronic materials. In addition, we combine the best of two worlds by welcoming researchers from all over the world and by teaching local students from Bern.
This combination of different backgrounds and experiences forms a powerful symbiosis that enables us to understand the underlying principles of charge transport in the materials we study.
Our research interests
Our objective is to understand fundamental material properties (e.g., light–matter interactions, electron transfer processes, charge transport, molecular recognition) of organic and hybrid semiconductors, with applications in new generation solar cells, organic transistors, and organic bioelectronics. The current gap between missing fundamental understanding and the blind development of applications needs to be filled in order to achieve intelligent design of high-performance devices.
Our research revolves around the central question of what happens on the ultrashort time scale and ultrasmall length scale in organic solids to induce macroscopic function in devices, and how this can be optimized. Experimentally, we use a complementary palette of techniques combining (time-resolved) spectroscopy, pulsed photocurrent methods, terahertz experiments, Stark-effect spectroscopy, and device testing.

New research published!
We are pleased to announce a new publication entitled “Sensitive Self-Driven Single-Component Organic Photodetector Based on Vapor-Deposited Small Molecules” where we collaborated with Jakob to investigate a single-component organic photodetector (OPD). Many thanks to Johannes Benduhn and Karl Leo for the collaboration on this project.

New research published!
We are pleased to share our new paper entitled ”Free Charge Carrier Generation by Visible-Light-Absorbing Organic Spacers in Ruddlesden–Popper Layered Perovskites”. Combining multiple spectroscopic techniques, the increase of light harvesting and the generation and spatial separation of charge carriers in the new synthesized (NDI-DAE)2PbI4 has been demonstrated. Many thanks to Kevin Sivula group at EPFL […]

Welcome Alan!
We warmly welcome Alan Eduardo Ávila Ramírez in our group! He is joining FemtoMat for a PhD project where he will investigate the electrochemical doping of organic mixed ionic-electronic conductors for the ICONIC (In-situ & operando organiC electrochemical transistors monitored by non-destructive spectroscopies for Organic cmos-like NeuromorphIc Circuits) project. All the best for the start!
