Researchers from the University of Utah have managed to control and read spin information at room temperatures. For this experiment, they used an orange OLED device.
The researchers were able to read the nuclear spins of two hydrogen isotops: a single proton and deuterium (a proton, neutron and electron). When the researchers controlled the spin, they controlled the electrical current in the device.
The ability to control and read spin information at room temperature is very exciting. It may lead to better spintronics applications in memory devices and data processing - and may even enable researchers to build better performing OLEDs using spin information (this is not a new idea).
