The handedness or “chirality” of electrons affects how current flows in graphene transistors, according to new work done by researchers in the UK and Russia. The team’s findings could help to make ...

Physicists have made the first definitive measurements of "persistent current," a small but perpetual electric current that flows naturally through tiny rings of metal wire even without an ...

Where the current flows: Schematic of a SQUID pickup loop imaging stray magnetic fields above a Hall bar sample of dimensions 200 × 75 μm. (Courtesy: Adapted from G M Ferguson et al. Direct ...

“But locally, on one edge, the current flows in the other direction so a being that lives on that surface would observe very strange physics!

Gallium oxide (Ga₂O₃) is a semiconductor material that could make electronic devices much more energy-efficient than current ...

What looks like ordinary sand, rocks or snow flowing in one direction can actually hide swirling currents that move in ...
