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 ...

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 ...
