Technological innovation in the last century was mainly based on the control of electrons or photons. Now, in the emerging research field of phononics, phonons or vibrations of the crystal lattice ...

Superconductivity is an advantageous physical phenomenon observed in some materials, which entails an electrical resistance ...

Apr 30, 2014: Researchers manage to change the crystal structure of graphene in a controlled fashion (Nanowerk News) A University of Arizona-led team of physicists has discovered how to change the ...

Graphene consists of a single atomic layer of carbon, arranged in a honeycomb lattice. "Our first Science paper, in 2008, studied the strength graphene can achieve if it has no defects -- its ...

A pristine sample of graphene. In the new work, which is detailed in Nature, researchers led by Princeton’s Ali Yazdani used a scanning tunnelling microscope (STM) to study electrons in a pristine ...

Grain boundaries in polycrystalline graphene are an obstacle to electron transport. However, cunning refinements in growth techniques push the limits to obtain super-sized single-crystal domains.

This has to be done in a very controlled way because of a peculiarity of the graphene’s crystal lattice, which consists of two sublattices. Gonzales-Herrero et al. deposited a single hydrogen atom on ...

A new way of modifying the electronic properties of graphene has been discovered by a team led by Andre Geim and Kostya Novoselov at the University of Manchester. The physicists have shown that when ...

Graphene, a nanocarbon material just 0.3 nanometers thick and 200 times stronger than steel, is starting to revolutionize construction. Discovered in 2004, graphene’s unique hexagonal crystal ...
