Skilled and committed employees are a crucial factor in the success of Linköping University. And we need more of them. Our core expertise comes from teachers and researchers, but a successful university requires experienced and motivated employees in many fields. Everyone is important. We need to recruit many new employees thanks to, among all, an expansion in our research activity. We need you here. We look forward to receiving your application!

We are now looking to appoint a postdoc in Molecular Computational Spectroscopy, placed at the Laboratory of Organic Electronics, Department of Science and Technology, Campus Norrköping.

The Laboratory of Organic Electronics belongs to the Department of Science and Technology and is renowned for its world-leading research on electronic and optical devices based on organic materials. Its primary theme involves the coupling of ions and electrons as signal carriers for applications in organic bioelectronics, printed electronics, organic energy and electrochemical devices, and nanooptics. Currently, the research staff of the Laboratory includes about 120 researchers (professors, senior and junior scientists and PhD students), see http://liu.se/loe for detail.

Research area.

Light emission diode technology has undergone a rapid development in the last 20 years, defining a steeply growing worldwide market that comprises small devices like smart phones, tablets, TV displays and lighting apparatuses. Organic light-emitting diodes (OLEDs) have great potential for application as alternative to traditional inorganic light sources with fabrication that is cheap, environmentally friendly and simple. However, despite the significant advances in the area of organic lighting, the main principles and mechanisms of OLED emission are still of great relevance for research. In particular, this holds for the principles of electroluminescence of radical-based OLEDs. Such devices utilize doublet-doublet emission by organic luminescent radicals (OLRs) – systems containing odd number of electrons and one unpaired electron occupying single molecular orbital. However, the mechanisms of electroluminescence by radicals are very different and more complex comparing to conventional OLEDs based on closed-shell diamagnetic emitters – systems containing even number of electrons and pairwise occupancy of highest occupied and lowest unoccupied molecular orbitals.

Duties
Principles of doublet fluorescence and the role of quartet excited states in luminescence by radicals are of high relevance. The current project aims to design new OLRs for utilizing them in radical OLEDs with absolute internal quantum efficiency 100% by using modern quantum-chemical approaches including calculations of radiative doublet-doublet fluorescence, doublet-quartet phosphorescence and nonradiative internal conversion and inter-system crossing pathways of excitation energy dissipation. To accomplish that the key important challenges will be addressed: i) how to make organic radicals as bright and stable as possible at the same time; ii) how to enhance the efficiency of radical-based OLEDs (practical recommendations); iii) how to make radicals phosphorescent.

In order to realize the proposed project in most efficient way there are several important competences are required from potential candidate: 1) Deep knowledge in molecular spectroscopy and understanding the principles of light-matter interactions at advanced level; 2) Experience in modern computational techniques (especially in multireference ab initio approaches) for calculations of electronic structure and excited states of many-electron systems. 3) ability to analyse large data sets and to extract most important results from them; 4) expertise in systematization of results and building the logical schemes for purposeful molecular design.

Qualifications
To be qualified to take employment as postdoc, you must have been awarded a doctoral degree or have a foreign degree that is deemed to be equivalent to a doctoral degree.  This degree must have been awarded at the latest by the point at which LiU makes its decision to employ you.

It is considered advantageous if your doctoral degree is no older than three years at application deadline for this job. If there are special reasons for having an older doctoral degree – such as taking statutory leave – then these may be taken into consideration.

The applicant must have or be about to receive a doctoral degree in a subject relevant to the research project (e.g. PhD in computational chemistry, chemical physics or similar) and needs to be passionate about research. Problem solving ability and creativity are essential.

Experience in usage Gaussian, ADF, Dalton, ORCA, QChem etc. software and parallel computing is required. Skills in data processing and visualizing the results of quantum-chemical simulations are strongly desired (Molden, ChemCraft, VMD etc. software).

Experience in excited electronic state theory is very important, i.e. experience in TDDFT, TDA-TDDFT, spin-adapted and spin-flip TDDFT, CASSCF, CASPT2, ADC(n) methods is crucial for this postdoc position.

In order to communicate with experimentalists (synthetic chemists and experts in device engineering) the basic knowledge in organic chemistry and organic electronics are needed as well as ability to prepare reports, presentations and drafts of manuscripts.

Great emphasis will be placed on personal qualities and suitability.
