Long sought-after material could revolutionize electronics
“Spintronics is a new, very promising (although still in its infancy) technology in which the intrinsic spin of electrons, rather than the value of a voltage like in today’s electronics, is used to store and transport information to be interpreted as either a “1″ or a “0″. The materials most apt to use in the field of spintronics are what experts call topological insulators, something that scientists have been searching for years and have now finally found in bismuth telluride. Topological insulators have the property of opposing no resistance at all to an electrical flow next to their surface, thus allowing for minimal heat dissipation.”
