Research

Semiconductor Device Materials

Our research focuses on the development of novel semiconductor materials for high-frequency and power electronics.

News

Two pipettes poring liquids on to a disk.

Research for a sustainable future in ten new projects

Photosynthetic materials, two-dimensional noble metals and sustainable semiconductors are some of the projects at LiU that have been granted funding from the research programme Wallenberg initiative materials science for sustainability – WISE.

Unique instrument shines through most everything

Low-frequency light reveals internal structures and properties in all conceivable materials. A research team at LiU has built a one-of-a-kind spectrometer that analyses samples with electromagnetic waves in the terahertz range.
