Sentences with phrase «hole in graphene»

Some researchers are investigating other promising ways to make graphene an effective semiconductor, like using two - layer graphene along with a special insulating polymer or punching holes in graphene to create a semiconducting «nanomesh,» but it remains to be seen if any of these techniques will produce viable chips.

Using a technique they developed last year, the researchers then etched tiny, uniform holes in graphene — small enough to let water molecules through, but not larger contaminants.

Not exact matches

By drilling holes in a hexagonal pattern in a sheet of perspex, researchers in Spain have created what they have dubbed «sonic graphene».

Specifically, in this work he has applied geometric structures similar to those of a crystal or graphene layer, not typically used to describe black holes, since these geometries better match what happens inside a black hole: «Just as crystals have imperfections in their microscopic structure, the central region of a black hole can be interpreted as an anomaly in space - time, which requires new geometric elements in order to be able to describe them more precisely.

They demonstrated that a sheet of graphene, a lattice of carbon atoms one layer thick, could be used to differentiate between bases in a strand of DNA by poking a tiny hole in the sheet and threading DNA through it.

Scientists have found that the charged particles in graphene behave like a relativistic fluid, meaning graphene - based chips could now be used to model black holes and supernovas or build highly efficient devices that turn heat into electricity.
