Researchers have identified a class of quantum materials, called topological semimetals, that can split water into hydrogen fuel using nothing but sunlight, sidestepping the expensive platinum-based ...

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 ...

Topological semimetals and metals have emerged as a new frontier in the field of quantum materials. Novel macroscopic quantum phenomena they exhibit are not only of fundamental interest, but may hold ...

Researchers from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS), in collaboration with ...

Imagine how much you could accomplish if the circuits in your laptop and cell phone worked 10 times faster, and your battery lasted 10 times longer, than they do now. In order to understand the ...

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 ...

The observation of an abnormal state of matter in a 2-D magnetic material is the latest development in the race to harness novel electronic properties for more robust and efficient next-generation ...

(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 ...

When topological nodal semimetals are placed in a strong magnetic field, they become very good at converting heat current into electric power. That’s the new result from researchers at the ...

Researchers have measured high conductivity in very thin layers of niobium arsenide, a type of material called a Weyl semimetal. The material has about three times the conductivity of copper at room ...
