My research interests range from fundamental charge and energy transport in disordered, mostly organic semiconductors, to device concepts and applications based on these materials.

Background

I obtained a Master degree in Applied Physics from Eindhoven University of Technology in the Netherlands in 1993. In 1998 I received a PhD from the same university (Thesis ‘Many-body effects in the valence bands of two-dimensional heterostructures based on III/V semiconductors’). After that I was awarded a 5-year post-doctoral fellowship from the Netherlands Academy of Arts and Sciences (KNAW) to work on scanning tunneling spectroscopy and STM-induced luminescence. During this fellowship I shifted my attention from inorganic, highly crystalline semiconductors to organic, amorphous or polycrystalline semiconductors. I became assistant professor in 2003 and associate professor in 2009. As of 2014 I have been appointed full professor in Applied Physics at the Department of Physics, Chemistry and Biology (IFM) at Linköping University in Sweden, where I lead the group Complex Materials and Devices (CoMaDe). 

Research

My research interests range from fundamental charge and energy transport in disordered, mostly organic semiconductors, to device concepts and applications based on these materials. The group's websites and the publication list below should give a reasonable indication of what this means in practice.

Water creates traps in organic electronics

Poor-quality organic semiconductors can become high-quality when manufactured correctly. Researchers at Linköping University have shown that the motion of charges in organic electronic devices is dramatically slowed by minute amounts of water.

Ferroelectricity – an 80-year-old mystery solved

Only now in 2018 have researchers successfully demonstrated that hypothetical ‘particles’ that were proposed by Franz Preisach in 1935 actually exist. In an article published in Nature Communications, scientists show why ferroelectric materials act as they do.
Light-emitting electrochemical cell

The light comes from LECs

Researchers at Linköping University and Umeå University have succeeded in increasing the efficiency of light-emitting electrochemical cells so their luminance equals that of a panel of OLEDs, and their efficiency is on a par with a fluorescent lamp.

Complex Materials and Devices

The division research focuses on innovative device concepts which are made possible by the specific properties of the active material(s) from which they are built.

LiU doctoral student to meet Nobel laureates

Tim Cornelissen, IFM, is one of the young researchers invited to this year’s Lindau Nobel Laureate Meeting in Germany. 580 undergraduates, doctoral students, and postdocs will have the opportunity to meet and discuss science with Nobel laureates.
