NU lab's findings could increase microchip efficiency
Computers have been getting smaller and smaller from the time they were first constructed. A calculator that would have once filled an entire room can now easily fit in an engineer's pocket. But there is a limit to how small a computer's components can get -- the size of a single molecule. Now a team of Northwestern scientists might have broached that limit. The group measured a type of electrical flow through a single molecule mounted on silicon, a finding which would make the molecule useful as a semiconductor, the essential component of a computer chip.
