Tiny nanoparticles improve charge transport
Bielefeld researchers publish study on topological insulators
Three-dimensional topological insulators are materials that can conduct electric current without resistance—but only on their surface. However, this effect is difficult to measure. This is because these materials usually have little surface area in relation to their volume, which means their transport properties are dominated by bulk charge carriers. Bielefeld University physicists have now succeeded in developing topological insulators based on tiny nanoparticles and have thus been able to demonstrate charge transport on the surface. The study was conducted in cooperation with researchers from the University of Duisburg-Essen and the Leibniz Institute for Solid State and Materials Research Dresden. The scientists have published their results today (21.9.2021) in the journal Small. The European Research Council ERC funded the study with a Consolidator Grant.
