Graphene Currents…

Topics: Materials Science, Nanotechnology, Quantum Mechanics, Semiconductor Technology A team led by researchers from Harvard University and the University of Maryland in the US has used defects in diamond to map the magnetic field generated by electrical currents in graphene. Their experiments reveal that currents in this atomically-thin form of carbon flow like a viscousContinue reading “Graphene Currents…”

Bright, Tiny, Powerful…

Topics: Light-Emitting Diode, Nanotechnology, Solid-State Physics A new design for light-emitting diodes (LEDs) developed by a team including scientists at the National Institute of Standards and Technology (NIST) may hold the key to overcoming a long-standing limitation in the light sources’ efficiency. The concept, demonstrated with microscopic LEDs in the lab, achieves a dramatic increaseContinue reading “Bright, Tiny, Powerful…”
