Topological crystals are a revolutionary class of materials that exhibit unique electronic and physical properties due to their non-trivial topological band structures. These materials have garnered ...

Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...

Plutonium is one of the most complex elements in the periodic table. First synthesized and isolated in 1940 by scientists at the University of California, Berkeley, plutonium has been studied closely ...

Topological materials can be categorized into several types, including topological insulators, topological superconductors, and topological semimetals. Each type exhibits unique electronic properties ...

"Our method shows that the topological contribution is fundamentally robust enough for practical applications," Fijalkowski says. "Now we need to find a way to reduce the additional conductivity in ...
