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 ...

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 ...

Is it really worth building a device with a screen if it can’t play Doom? Of course not, which is why Sean Hodgins recently shared a video justifying the existence of their custom built persistence-of ...

The first layer is a semitransparent anode, such as ITO, that injects unpolarized "holes," a quantum feature of electrons, with a certain spin. The second layer is the two-dimensional chiral hybrid ...

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 ...
