Kort presentation
I am a solid state physicist focusing on understanding the physics of nano materials such as thin films. My research interests involve hydrogen uptake in metals, and their impact on physical properties of nano materials. The hydrogen team uses a problem based approach to science, and we tailor-make samples to address specific scientific questions. We use optical, x-ray, and neutron scattering to see where the hydrogen goes and spectroscopic methods to understand what the hydrogen does.
Nyckelord
