Graphene likely to replace silicon in computer chips
Bangalore: To make the chips work 100 to 1,000 times faster than silicon, scientists have developed a way to put the graphene on 4-inch wafers. Graphene is a crystalline form of carbon that is made up of two-dimension hexagonal arrays which is ideal for electronic applications. David Snyder and Randy Cavalero at Penn State said that they came up with a method called silicon sublimation that removes silicon from silicon carbide wafers and leaves pure graphene. Some scientists had tried similar process to use graphene before, but it is being claimed by EOC that they are the first group which has perfected the process to a point that lets them produce 4-inch wafers, reports Electronista. By using the smallest wafers in a more conventional method have resulted in 8-inch graphene wafers. The processors which are used now-a-days are roughly 11 inches across.
