Researchers in the US have made the most convincing measurement yet of the bizarre electronic property that has earned topological insulators their recent fame. The team has shown that the electron ...

Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an ...

Okay, I admit that the title sounds a bit like a contradiction in terms, but I am actually making sense—well, sort of. Most high-temperature superconductors are manufactured from layers of oxides, ...

An intrinsic magnetic topological insulator MnBi2Te4 has been discovered with a large band gap, making it a promising material platform for fabricating ultra-low-energy electronics and observing ...

RIKEN physicists used the tip of a scanning tunneling microscope (gray inverted pyramid) to inject single electrons (gold sphere) into the surface of a Mott insulator. (Image: RIKEN Center for ...

Insulator or superconductor? Physicists find graphene is both, at a 'magic angle.' It's hard to believe that a single material can be described by as many superlatives as graphene can. Since its ...

(Nanowerk News) New energy-efficient electronic devices may be possible thanks to research that demonstrates the quantum anomalous Hall (QAH) effect -- where an electrical current does not lose energy ...

Spin orbits: spiralling electrons on the surface of bismuth selenide produce circularly-polarized light. (Courtesy: iStock/VikaSuh) The first ever observations of chiral surface excitons have been ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. Scientists in Canada have shown off a groundbreaking way of controlling electrical currents at will by altering the ...

Normally metals and insulators sit at opposite ends of a spectrum of conductivity, but researchers have discovered a material that can switch between those states freely, even at room temperature. The ...

ITHACA, N.Y. - Quantum mechanics can seem a bit confounding, so for a quantum material to be called "strange" is really saying something. A Cornell University-led collaboration has used ...

CAMBRIDGE, MASS.--It's hard to believe that a single material can be described by as many superlatives as graphene can. Since its discovery in 2004, scientists have found that the lacy, honeycomb-like ...
