Science Daily  March 14, 2018 Researchers in Italy have demonstrated that hexagonal graphene nanoflakes with zigzag edges display quantum interference. In “Quantum interference transistors” destructive interference would be the “OFF” status. For the “ON” status, they say it is sufficient to remove the conditions for interference. They also demonstrated that magnetism emerges spontaneously at their edges, without any external intervention. This enables the creation of a spin current. The union between the phenomena of quantum interference and of magnetism would allow to obtain almost complete spin polarization, with a huge potential in the field of spintronics. These properties could be […]
