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 ...
(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 ...
Researchers at Peking University and collaborators have revealed evidence of Mott insulator with thermally induced melting ...
Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling ...
Looking only at their subatomic particles, most materials can be placed into one of two categories. Metals — like copper and iron — have free-flowing electrons that allow them to conduct electricity, ...
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 ...
Nanoribbons are promising topological materials displaying novel electronic properties. Chemists and physicists have found a way to join two different types of nanoribbon to create a topological ...

Dec. 16 (UPI) --The phenomenon known as the quantum anomalous Hall effect describes the ability of electrons to move freely along at the outer edges of materials. Electrons propelled by the QAH effect ...
In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a ...
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 as it flows ...
