Head of the Laboratory of Mathematics, Physics and Electrical Engineering (MPE-lab) at Halmstad University since 2005. The research of our group is focused on electrical, optical and magnetic nanoscale devices for future integrated electronics and photonics. The research is done in close collaboration with the Nanometer Structure Consortium at Lund University. We also have extensive collaboration with Harvard University (prof. F. Capasso), IBM-Almaden (prof. S. Parkin), Kalmar University (prof. C. Canali) and Acreo (dr. J. Andersson and dr. L. Höglund).
Pettersson´s research was initially focused on studies on electronic properties of deep impurities in silicon using junction space-charge techniques in the group of prof. H. G. Grimmeiss (div. of solid state physics at LU). In 1996 his main research field switched towards physical properties of nanoscale devices, in particular electrical and optical properties of self-organized semiconductor quantum dots (group of prof. L. Samuelson at LU). Between 1997 and 1999 he was a post-doc at the Ludwig-Maximilians Univ. in Munich (group of prof. J. P. Kotthaus) working on absorption spectroscopy on quantum dots and low-temperature AFM. In 1999 he received a permanent position as lecturer in physics at Halmstad University, continuing his research on fundamental electrical and optical properties of self-assembled quantum dots & wires, and their application in e.g. memory devices and infrared photodetectors. He has successively broadened his research to other areas of nanoscience including spintronics and nanotribology.
Pettersson has authored, or co-authored, about 60 journal publications, 70 conference papers and 1 book chapter. About 15 popular scientific presentations including television and radio programmes. He has given more than 30 invited talks.
Pettersson has also been deeply involved in teaching and third assignment activities. He has developed and given numerous physics courses (A, B and C-level). He has supervised numerous bachelor students and master students. Between 2001 and 2006 he was director of studies for the physics teacher programme at Halmstad University (HU). He is presently coordinating an international Master programme in microelectronics, photonics & nanotechnology. He has also been engaged in popularizing physics and technology by arranging several experimental workshops for students from ”gymnasium” and ”grundskola”. He was initiator of the Campus observatory at HU (Frida Palmér observatoriet), built in 2002.
