Materials and Nano Physics

The Materials Physics groups perform basic and applied research in the areas of Surface physics, Strongly correlated systems, Spintronics, and Nanosilicon

The Material Physics unit consists of approximately 10 senior staff members and 20 junior staff members. The main areas of activity are related to surfaces, interfaces, correlation effects, magnetism and nano-structures. We have in-house access to world class facilities in the areas of micro and nano-fabrication, electron and scanning probe microscopy as well as spectroscopy. Our staff are also large users of national and international synchrotron radiation facilities such as Maxlab, the Swiss Light Source and the European Synchrotron Radiation Facility. Teaching is the other main activity of our staff and we are responsible for basic physics teaching as well as specialized and graduate courses. More detail about our research is given on the group pages.

Strongly Correlated Systems

Charge density picture

Research within the field of strongly correlated materials deals with the understanding of collective phenomena that emerge when the electrons within a material can no longer be treated as independent particles. Magnetism and superconductivity are prime examples of such collective phenomena. Our present research is focused on high temperature superconductivity, magnetism, transition metal- and rare earth systems.

Nano Silicon

Oxidized Si nanopillar

Nano-structured materials have the prospect of many applications in the near future. Here we focus on nanostructured silicon including nanowires, nanopores and quantum dots. Nanowires show promises as bio-molecule sensors while micro- and nanopores have applications in X-ray imaging. Silicon nanocrystals, finally, show quantum confinement with efficient, tunable visible luminescence.

Surface Physics

Within the field of surface and interface physics we conduct research concerning surface electronic structure and surface chemistry. Surface chemistry related to catalysis and Grätzel solar cells are areas of particular interest.


Magnetism is a subject of intense research and its different aspects is a topic of research in several of the department groups. In the spintronics group the focus is on applications of magnetism in devices. Currently we are focusing our efforts on the development and characterization of spin torgue oscillators.

Ultrafast Electron Microscopy

We are interested in following the reorganization of atoms and elections as materials undergo change in state, through reactions, translations, or transitions. Under a recently awarded Knut and Alice Wallenberg Foundation (KAW) infrastructure project we will construct the first UEM, also called dynamic TEM, in Sweden. The instrument will facilitate the recording of “movies” of the motion of atoms as they are in transition.
