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.

Organisation

A light-green thin sheet is immersed in water.

Semiconductor Materials (HALV)

Our division develops and investigates materials for novel electronics with the main focus on silicon carbide, III-nitrides and graphene.

Department of Physics, Chemistry and Biology (IFM)

Excellent undergraduate teaching and research in the areas of biology, chemistry, materials and applied physics and theory and modelling are conducted at this department.
