Will Graphene Replace the Silicon Chip?
A pair of Nobel laureates have created a multi-layer transistor made of graphene. The new design succeeds where past models failed, begging the question: Will graphene replace silicon chips?
What's the Latest Development?
A pair of Nobel laureates have created what might become the replacement to the silicon computer chip. Professor Andre Geim and Professor Konstantin Novoselov have constructed a multi-layer graphene transistor which succeeds where past models have failed. Specifically, their model layers the atomically thin graphene molecules vertically rather than horizontally, as has been done in the past. The professors have taken advantage of a unique characteristic of graphene to 'change the energy gap of tunneling electrons'.
What's the Big Idea?
The potential of graphene, at once the world's strongest and most conductive material, has already caught the attention of important computer manufacturers like IBM, Samsung, Texas Instruments and Intel. While problems persist--current graphene transistors leak too much energy, easily overheating and melting chips--manufactures are eager to replace silicon because of current speed limitations. At stake is Moore's Law which has correctly predicted the doubling of computer power about every 18 months.

- The case is still open, and the administration may choose to appeal the ruling.
Progressive America would be half as big, but twice as populated as its conservative twin.
- The new definition of a kilogram is based on a physical constant in quantum physics.
- Unlike the current definition of a kilogram, this measurement will never change.
- Scientists also voted to update the definitions of several other measurements in physics.
