Weyl semimetals are topological materials whose low-energy excitations obey the Weyl equation. In a Weyl semimetal, the conduction and valence bands touch at discrete points in momentum space called ...
Using the symmetries of the systems, people can define various topological invariants to describe different topological states. The topological materials can be accurately discovered by calculating ...
Weyl semimetals are characterized by their electronic structure, where conduction and valence bands touch at points called Weyl nodes. These nodes occur in pairs with opposite chirality, leading to ...
Semimetals promise more efficient conductivity, outperforming copper in energy use Copper’s limitations drive the search for semimetals like niobium phosphide Niobium phosphide conducts electricity ...
(Nanowerk Spotlight) Topology is the branch of mathematics that explores the nature of shapes independent of deformation. Physicists developed the concept of the phases of matter with properties that ...
A technical paper titled “Layered semimetal electrodes for future heterogeneous electronics” was published by researchers at IIT Madras and Indian Institute of Science Education and Research. Find the ...
“Contrary to topological insulators, topological semimetals possess a nontrivial chiral anomaly that leads to negative magnetoresistance and are hosts to both conductive bulk states and topological ...
