Dreidel-like dislocations lead to remarkable properties

(Phys.org)—A new material structure predicted at Rice University offers the tantalizing possibility of a signal path smaller than the nanowires for advanced electronics now under development at Rice and elsewhere.

Graphene mini-lab

A team of physicists from Europe and South Africa showed that electrons moving randomly in graphene can mimic the dynamics of particles such as cosmic rays, despite travelling at a fraction of their speed, in a paper about ...

Infrared absorption boosted by layering sheets of graphene

(Phys.org)—Since its discovery in 2004, graphene has been hailed as a "wonder material" due to its almost unbelievable properties. At just one atom thick, a single two-dimensional layer is stronger than diamond, conducts ...

The secrets of tunneling through energy barriers

Electrons moving in graphene behave in an unusual way, as demonstrated by 2010 Nobel Prize laureates for physics Andre Geim and Konstantin Novoselov, who performed transport experiments on this one-carbon-atom-thick material. ...

Graphene applications in electronics and photonics

Graphene, which is composed of a one-atom-thick layer of carbon atoms in a honeycomb-like lattice (like atomic-scale chicken wire), is the world's thinnest material – and one of the hardest and strongest. Indeed, the ...

Quantum simulator prototype replicates structure of graphene

(PhysOrg.com) -- A team of researchers from Columbia Engineering, the Italian National Research Council, Princeton University, University of Missouri, and University of Nijmegen (Netherlands) has developed an artificial semiconductor ...

Defect in graphene may present bouquet of possibilities

(PhysOrg.com) -- A class of decorative, flower-like defects in the nanomaterial graphene could have potentially important effects on the material's already unique electrical and mechanical properties, according to researchers ...
