Stanene may be better than Graphene
December 06, 2013 // By R. Colin Johnson
A team of researchers led by Stanford University professor Shoucheng Zhang now have high hopes that a new material they call stanene will conduct electricity on next-generation microchips with "100 percent efficiency" at room temperature and above.
In practice, stanene interconnection lines will behave like dual side-by-side superconducting wires, since each ribbon of stanene will support two lanes of zero resistance data traffic -- one on each edge. The only resistance offered by a stanene interconnection line would be at the end points where a contact must be made with the traditional on-chip circuitry.
"The key difference is that with a normal conductor, the total resistance scales linearly with the length -- the longer the wire the larger the resistance," said Zhang. "But for stanene the only resistance is the contact, so the total resistance of a line is constant regardless of the wire's length."All news
