Physicists propose explanation for metals behaving badly
Highly conductive organic metal looks promising for disposable electronic devices
Metallic-to-semiconducting nanotube conversion greatly improves transistor performance
Inkjet-printed graphene electrodes may lead to low-cost, large-area, possibly foldable devices
Physicists show unlimited heat conduction in graphene
Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the National University of Singapore have attested that the thermal conductivity of graphene diverges with the size of the ...
Missing link in metal physics explains Earth's magnetic field
Earth's magnetic field is crucial for our existence, as it shields the life on our planet's surface from deadly cosmic rays. It is generated by turbulent motions of liquid iron in Earth's core. Iron is a ...
Accidental discovery dramatically improves electrical conductivity
Quite by accident, Washington State University researchers have achieved a 400-fold increase in the electrical conductivity of a crystal simply by exposing it to light. The effect, which lasted for days after ...
Electrons are not enough: Cuprate superconductors defy convention
(Phys.org) —To engineers, it's a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania ...
New studies explain insulator-to-metal transition of vanadium dioxide
When heated to just above room temperature, the electrical conductivity of vanadium dioxide (VO2) abruptly increases by a factor of 10,000. Experiments coupled with high-performance computation reveal how ...
New mechanism of photoconduction could lead to next-generation excitonic devices
It's a well-known phenomenon in electronics: Shining light on a semiconductor, such as the silicon used in computer chips and solar cells, will make it more conductive. But now researchers have discovered ...
