RESEARCH

Per-Olof Nilsson


On 1 September 2006 I finished my carrier in physics research. My research area was of basic nature and aimed at a better understanding of the electronic structure of various types of solids. Such knowledege is the key to the understanding of material properties. During the last period I in particular studied semiconductor interfaces and diluted alloys. Fundamental understanding of such structures is of obvious importance for the development of various technologies (e.g. micro-electronic devices).

The tools I applied included photoelectron spectroscopy (PES), soft x-ray emission and absorption spectroscopy (SXE and SXA) using synchrotron radiation. In fact, with colleagues, I was the first to perform angle-resolved photoemission measurements, now a widely used technique. A special contribution was my initiative to build the synchrotron radiation source MAX-lab in Lund, Sweden. In many cases I also applied full-scale ab initio computations on the electronic structure, often in parallel with the experiments.

My research has resulted in about 200 refereed articles in well-know international journals. My publication list is here. Many more contributions (about 200) at conferences etc are not documented here.

Since 2006 I work full time with an activity, House of Learning, which I created myself. This includes, among other things, a unique science center with more than 300 hands-on experiments. Other activities are a weekly science caf named Caf--lr (see www.cafealar.se), teachers' re-education, science shows and much more (see www.larandetshus.se).
