The idea of a fan with LEDs that spell out words as it spins is nothing new, but here’s one that’s programmable via USB. Polo Tech from Taiwan has patented a rotating LED fan display technology that ...

The inclusion of a special new perovskite layer has enabled scientists to create a "spin-polarized LED" without needing a magnetic field or extremely low temperatures, potentially clearing the path to ...

Scientists transformed existing optoelectronic devices into ones that can control electron spin at room temperature, without a ferromagnet or magnetic field. Researchers replaced the electrodes of ...

Stack of the spin-LED emitting circularly polarized electroluminescence. The (R-MBA 2 Pbl) acts as a spin filter, allowing only polarized carriers (blue circles) to flow through the LED and recombine ...

(Nanowerk News) Traditional electronics use semiconductors to transmit data through bursts of charged carriers (electrons or holes) to convey messages in “1s” and “0s.” Spintronic devices can process ...
