Sentences with phrase «nanoribbons as»

Hu, Ruan, and Chen also published a paper four years ago in the journal Nano Letters, among the first to propose asymmetric graphene nanoribbons as a thermal rectifier in research using the molecular dynamics simulations.

Not exact matches

Triangular graphene nanoribbons (a) are proposed as a new thermal rectifier, in which the heat flow in one direction is larger than that in the opposite direction.

Ultimately, the model could be applied to semiconductors used as high - efficiency thermoelectrics, and to graphene nanoribbons used as heat sinks for so - called ultra large scale integration devices, such as computer microprocessors.

Various methods of making graphene - based field effect transistors (FETs) have been exploited, including doping graphene tailoring graphene - like a nanoribbon, and using boron nitride as a support.

«We are now able to watch as individual molecules join together to form nanoribbons of graphene and polymers.

But there are ways to give the material a band gap, including using two separated strips of graphene fabricated as «nanoribbons.»

The researchers discovered that all nanoribbons become rigid under stress, but their rigidity increases as oxide molecules are removed to turn graphene oxide nanoribbons into GNRs.

Sorkin and Su's calculations give further insights into these systems, indicating that as they point out in their report, «the intermediate structure experiences disintegration followed by a remarkable re-building process to form graphene nanoribbons with differently oriented grains.»
