What is it about?
Today, organic light emitting diodes (OLEDs) are everywhere around us: in smartphone and tablet displays, televisions, and computer screens. But can we use these devices also for optical communication, maybe even for superfast on-chip and chip-to-chip communication? And can we make fast switching organic lasers and photodiodes? In the EU Pathfinder project “High-Speed Organic Photonics and OptoElectronics” (HiSOPE) you will address these questions together with colleagues in Paris, Grenoble, Kaunas, St. Andrews and Glasgow. You will collaborate intensively with the software company Scientific Computing and Modelling (SCM), which develops the software for quantum mechanical modelling.
The research team
You will work in the group Molecular Materials and Nanodevices (M2N), which researches optoelectronic devices of organic and perovskite semiconductors. The group is embedded both in the department of Chemical Engineering and Chemistry (CEC) and the department of Applied Physics and Science Education (APSE), where you will be located. You will do theoretical/computational research, in close collaboration with experimental researchers.
What will you learn?
Your supervisor, Prof. Peter Bobbert, is an expert on quantum mechanical modelling of organic optoelectronic devices. He is co-developer of the scientific simulation software “Bumblebee”, which simulates the quantum processes taking place in these devices. You will learn how to work with this software and how to calculate from basic quantum mechanical principles the simulation input of this software, such as the energies of charges and excitons, and the rate with which these move (for an example, see https://www.youtube.com/watch?v=n1qkzv_Q7UU). You will also get acquainted with the growing use of AI in this research area. You will not only develop technical skills, but also personal skills on how to perform cutting-edge research in a mixed team of experimental and theoretical/computational researchers and how to publish your research in top journals. You will also be involved in education and learn to coach Bachelor and Master students.
Key challenge
There are experimental indications that switching speeds of OLEDs in the GigaHertz range are possible, but understanding is lacking. The first electrically driven pulsed organic laser has been realized last year by the St. Andrews group, but its limits are unexplored. Organic photodiodes can switch more quickly than expected, but their ultimate response is unknown. Understanding how the underlying quantum mechanical processes determine the ultimate switching speed of these devices is the key challenge and your modelling research will play a central role. Ultrafast optical communication with organic optoelectronic devices is a very attractive alternative to WiFi. The compatibility of organic semiconductors with silicon means that these devices are also attractive for on-chip and chip-to-chip communication through optical fibers. Your work can therefore contribute to technological breakthroughs.
