If things work well, we could be on the brink of seeing an organic ’spin transistor’. Physicists at the University of Utah have been able to control the electric current within an electron by using a ’spin’. Though organic LEDs have now been understood as not so efficient in converting electricity into heat, organic or ‘plastic’ LEDs are not only cheaper but also much easier to manufacture. The ‘spin’, which is an angular momentum of the particle in an atom, can be used to store and transmit information, which can be interpreted in a binary form for computer usage. Organic LEDs can instead be used in television and computer screens than domestic lighting purposes. Studies on ‘flip-flop’ have revealed that organic LEDs have an efficiency of about 25%. However, by changing the spin orientation or by ‘flipping’, efficiency of organic LEDs can be increased up to 63%. Though the research still needs time to produce better results and consolidated theories, the future does look bright for spintronics.
