Electron superhighway: Can graphene overtake silicon as the essential ingredient of computer chips?doi:10.1002/scin.2007.5591721310Davide CastelvecchiSociety for Science & the Public
graphene could, in theory, replace silicon as the primary semiconductor material in electronics that require high speed, low loss requirements, small-scale and flexibility. Graphene’s market is estimated to be approximately $190 billion USD across a wide range of areas including data...
Why Silicon Could Replace Carbon Anonode in EV Batteries One huge benefit of silicon anode is it has three times the energy density of carbon. Currently the only way to get more power/efficiency of a batter is to increase the amount of material per unit, thus driving up the battery’s en...
Trapped electrical charges in the silicon dioxide (a sort of atomic-scale dirt) can affect the electrons in graphene and reduce the mobility. Also, vibrations of the silicon dioxide atoms themselves can also have an effect on the graphene which is stronger than the effect of graphene’s own ...
根据最后一段But he suspects the world will soon shift to graphene chips,because silicon has such a head start."Most people working on silicon are bombed daily by new,wonderful materials that are about to replace it and none of it's ever happened," he says.(但他怀疑世界...
I think the supercap capacities of graphene can be laid flat in a very small space with a huge capacity. I could envision radio waves, which are energy always available in the air ,being harvested as a voltage and stored in a supercap. Why not? Report comment gkmac says: May 21, ...
s been a few decades since graphene was first identified as a potential nanomaterial in 1947, to be precise.Some scientists came up with the idea that a material like this can be used in a variety of ways but others are skeptical because really, how do you make a sheet of material that...
the scientists had to use special methods originally developed by former MIT postdoc Bai Song. More work will be needed to determine whether cubic boron arsenide can be made in a practical, economical form, much less replace the ubiquitous silicon. But even in the near future, the researchers...
According to the author, carbon conducts electricity at smaller sizes better than silicon, which is the traditionally choice for computer chips, and could eventually replace silicon as the material of choice...
(PhysOrg.com) -- "Graphene has been the subject of intense focus and research for a few years now," Philip Kim tells PhysOrg.com. "There are researchers that feel that it is possible that graphene could replace silicon as a semiconductor in electronics."
