Could graphene replace silicon?
Scientists at the University of South Florida (USF) have created an anomaly that could allow graphene to eventually replace silicon as the primary material in electronic devices.
Indeed, previous attempts at creating anomalies proved inconsistent and produced samples in which only the edges of thin strips of graphene or graphene nanoribbons contained a useful defect structure.

However, the USF team developed a method of producing a well-defined, extended defect several atoms across which contains octagonal and pentagonal carbon rings embedded in a perfect graphene sheet.
According to PhysOrg, the defect functions as a quasi, one-dimensional metallic wire that conducts electric current and can be used as metallic interconnects or elements of device structures of all-carbon, atomic-scale electronics.
To create the anomaly, the team used the self-organizing properties of a single-crystal nickel substrate, along with a metallic surface as a scaffold to synthesize two graphene half-sheets.
When the two halves merged, they naturally formed an extended line defect with a well-defined, periodic atomic structure and metallic properties within the narrow strip along the defect.
"This tiny wire could have a big impact on the future of computer chips and the myriad of devices that use them. In the late 20th century, computer engineers described a phenomenon called Moore's Law, which holds that the number of transistors that can be affordably built into a computer processor doubles roughly every two years," explained PhysOrg.
"This law has proven correct and society has been reaping the benefits as computers become faster, smaller and cheaper. In recent years, however, some physicists and engineers have come to believe that without new breakthroughs in new materials, we may soon reach the end of Moore's Law. [But] Metallic wires in graphene may help to sustain the rate of microprocessor technology predicted by Moore's Law well into the future."
Cheers mates,

Good information. I would also suggest readers to go through these voiCE posts. These are some latest updates.

Al-OtaibyCheers buddy for the support,
The links are very useful and directly related.
I really appreciate it 😀

praba230890It's happy to see about a thread on Graphene...I'm a graphene enthusiast... A single graphene layer couldn't make it but when a voltage is applied across two graphene layers separated it acts as semiconductor....If we make a transistor out of graphene it might be faster than silicon transistors by 10 times....

praba230890Molybdenite now competing with graphene in many aspects as the graphene lacks the band gap.
"In a 0.65-nanometer-thick sheet of MoS2, the electrons can move around as easily as in a 2-nanometer-thick sheet of silicon" . "But it's not currently possible to fabricate a sheet of silicon as thin as a monolayer sheet of MoS2."
The transistors made from molybdenite will use 100,000 times less energy in a standby state than traditional silicon transistors. sooner or later this molybdenite is going to replace the silicon as a two-dimensional material for replacing the three-dimensional silicon in transistors.
