Graphene to Power Future Computer Chips

It has been said for quite sometime that silicon will soon reach its limit as computer chips become smaller and faster. Graphene – a crystalline form of carbon is hailed as a successor to silicon. However, when graphene based chip are made using conventional deposition techniques, they tend to degenerate and lose their two dimension hexagonal arrays perfect for fabricating electronic devices. Basically, with conventional deposition techniques graphene turns to graphite, which is of no use in electronic chips.
