Operando and In-situ Multimode Characterization of Organic Semiconductors for a Comprehensive Design of High-Performance Electronic Devices

Organic semiconductors have emerged as a breathtaking prospect, promising a new era of electronic devices with unparalleled versatility and eco-friendliness. Their applications span a wide spectrum, encompassing organic light-emitting diodes (OLEDs) that bring life to vivid displays, organic photovoltaics (OPVs) that harness the sun’s energy, and organic field-effect transistors (OFETs) that drive the future of flexible electronics. Yet, to truly unleash their full potential across these diverse fields, we must grasp the profound intricacies governing structural order and morphology in thin films and their impact on charge transport. In this PhD project, we aim at pushing the boundaries of knowledge by operando and in-situ characterization of organic semiconductors thin films. This research work combines advanced characterization methodologies techniques, including x-ray diffraction, Scanning Probe Force Microscopy, and electrical measurements, to study the dynamic changes in material properties occurring during growth or thermal annealing and to achieve a microscopic understanding. Furthermore, the work will address the use of multi-component thin films paving the way for applications in NIR photo-detection and photo-thermal conversion.

Qualifications and Requirements:

A strong academic background in materials science, physics, or a related field, a curious and analytical mindset, and the will to learn experimental research.


Our group, the Physical Chemistry of Surfaces and Interfaces (PCSI)), has strong expertise in x-ray scattering techniques using synchrotron radiation as well as in advanced scanning probe microscopy.  Taking advantage of the relevant role that the PCSI group plays in the SPM platform of the InCAEM project, the doctoral thesis will include the combination of state-of-the-art methodologies that provide an exceptional environment for cutting-edge research. We offer a team-oriented, motivating work atmosphere, which will allow the candidate to develop independence and soft and technical skills.

Materials Science Institute of Barcelona (ICMAB-CSIC)

The work will be carried out at the Materials Science Institute of Barcelona (ICMAB-CSIC), a research center located at the UAB campus (~35 min from downtown Barcelona by public transportation). (ICMAB-CSIC) is a Severo Ochoa Excellence center focusing on cutting-edge research in functional materials in the fields of electronics, energy, and nanomedicine. With over 250 members from 30+ nationalities, ICMAB-CSIC offers a highly international and dynamic environment for enthusiastic young researchers.

Application Process:

Interested candidates are invited to contact Esther Barrena ( and Carmen Ocal ( and submit a CV.

NOTE: Only preselected applications will get an answer and will obtain an appointment to carry out an interview.

The position is intended to start around October 2023, financed under the project PID2022-136802NB-I00.

Please note that the deadline indicated is an estimation, and the position will remain open until we find the right candidate.
