Most popular articles for September 2015

• Reliable exfoliation of large-area flakes of graphene and other two-dimensional materials
by Huang  et al, ACS Nano

A paper describing a technique of exfoliating bulk layered crystals which gives flake sizes up to millimetre size. The technique relies on using oxygen plasma pre-treatment for the oxidized silicon substrate, which removes any adsorbed organics, and heating the substrate after the tape deposition in order to promote substrate-flake removal.

 Most popular 2D articles

Interesting times over at 2D Research as the most popular articles reflect the change of the overall field from graphene to other two-dimensional materials. Perhaps the paper with the most impact is the demonstration of massless Dirac fermions in layered zirconium pentatelluride. See below for more.

• Materials: Boron made into 2D sheet
by Editorial commentary Nature

An article from Nature highlighting a recent work published in Angewandte, demonstrating the growth of atomically thin boron films. The synthesis of boron seems to me an emerging area of science, with 3 other papers put online in December (Two on arXiv (1,2) and one published in Science).

This Angewandte article was also covered by a 2D Research editorial.

•  The observation of square ice in graphene questioned
by Zhou et al, Nature

Writing in Nature Zhou et al. question the previous Nature letter which presented evidence of two-dimensional square ice, trapped between two graphene layers. Their main evidence is two-fold. Firstly, they show that sodium chloride crystallizes in a structure akin to that presented in the initial article, and secondly show through simulations that the structure of a graphene-confined 2D ice does not have a perfectly square structure, rather a rhombic one.

In two accompanying replies to above, the authors of the initial paper still maintain that square ice can indeed be formed, since some of the features of the oxygen peaks do agree with recent theory work, although they do conclude that high resolution electron energy loss spectra looking for salts would unambiguously prove or disprove the contamination hypothesis. On the simulation front, the team shows that the rhomic, zig-zag structure is meta-stable, decaying into a square one in a matter of tens of nano-seconds, hence experimentally the lattice of ice will indeed show a square one.
