Spectroscopy and theory shed light on excitons in semiconductors

From solar panels on our roofs to the new OLED TV screens, many everyday electronic devices simply wouldn't work without the interaction between light and the materials that make up semiconductors. A new category of semiconductors ...

Driving photochemistry with sub-molecular precision

Absorption of light initiates many natural and artificial chemical processes, for example, photosynthesis in plants, human vision, or even 3D printing. Until now, it seemed impossible to control a light-driven chemical reaction ...

14 parameters in one go: New instrument for optoelectronics

An HZB physicist has developed a new method for the comprehensive characterization of semiconductors in a single measurement. The "Constant Light-Induced Magneto-Transport (CLIMAT)" is based on the Hall effect and allows ...
