Over the past two decades, physicists have been fascinated by semimetals — rare materials with zero energy gap, right at the threshold between metal and insulator. Some semimetals can host ...

Semimetals can be viewed as a kind of extreme limit of a semiconductor with zero 'energy gap', right at the threshold between insulator and metal. This extreme case remains exceedingly rare in real ...

Quantum sensors can be used to reveal a surprising new mechanism for converting light into electricity in Weyl semimetals, Boston College Assistant Professor of Physics Brian Zhou and colleagues ...

The thinner the film, the less good it is at conducting electricity. Topological semimetals are different. Analogous to the better-known topological insulators, which conduct electricity along special ...

This is a key step toward making hydrogen a viable, widespread energy source. Scientists make breakthrough discovery that ...

Rondinelli’s team is also modeling a subclass of polar metals called topological semimetals to address the interconnect bottleneck for further downscaling integrated circuits for microelectronics.

STANFORD researchers have developed a semimetal more conductive than copper, paving the way for an energy-efficient ...

Chiral Weyl fermions are massless particles first proposed in theoretical physics but found in condensed matter as excitations in Weyl semimetals. These materials are unique 3D phases with special ...

They’re also investigating other topological semimetals to find materials with even better conductivity. “For this class of materials to be adopted in future electronics, we need them to be ...

“Now we have another class of materials – these topological semimetals – that could potentially act as a way to reduce energy usage in electronics.” Because the niobium phosphide films don’t need to ...
