About this episode

Particles of the material bismuth telluride have unique properties: the interior of the particle acts as an insulator, but its surface can conduct electricity. In their recent research, Professor Gabi Schierning at Bielefeld University, Germany, and her collaborators at the University of Duisburg-Essen and IFW Dresden, offer fascinating insights into the properties of bismuth telluride particles. The team’s work may pave the way for their use in technological applications. More
