A new nanostructure acts like a wire and switch that can, for the first time, control and direct the flow of quantum ...
Scientists built a nano switch that controls excitons, chargeless quantum quasiparticles, at room temperature.
If you ever wished electrons would just behave, this one’s for you. A team from Tohoku, Osaka, and Manchester Universities has cracked open an interesting phenomenon in the chiral helimagnet α-EuP 3: ...
(Nanowerk News) Researchers at Dartmouth have built the world’s first superfluid circuit that uses pairs of ultracold electron-like atoms, according to a study published in Physical Review Letters ...
On a quest to discover new states of matter, a team of Princeton University scientists has found that electrons on the surface of specific materials act like miniature superheroes, relentlessly ...
If you are an EE you definitely know the answer to this, or at least you think you do. If you said positive to negative, you are wrong. Then you remember that current flow is a charge of electrons ...
Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...
