Unexpected catalytic activity of nanorippled graphene
P. Z. Sun, W. Q. Xiong, A. Bera +11
Graphite is one of the most chemically inert materials. Its elementary constituent, monolayer graphene, is generally expected to inherit most of the parent material's properties in…
2D materials and van der Waals heterostructures
K. S. Novoselov, A. Mishchenko, A. Carvalho +1
The physics of two-dimensional (2D) materials and heterostructures based on such crystals has been developing extremely fast. With new 2D materials, truly 2D physics has started to…
Molecular transport through capillaries made with atomic-scale precision
B. Radha, A. Esfandiar, F. C. Wang +13
Nanometre-scale pores and capillaries have long been studied because of their importance in many natural phenomena and their use in numerous applications. A more recent development…
Sieving hydrogen isotopes through two dimensional crystals
M. Lozada-Hidalgo, S. Hu, O. Marshall +6
One-atom-thick crystals are impermeable to atoms and molecules, but hydrogen ions (thermal protons) penetrate through them. We show that monolayers of graphene and boron nitride ca…
Proton transport through one atom thick crystals
S. Hu, M. Lozada-Hidalgo, F. C. Wang +10
Graphene is impermeable to all gases and liquids, and even such a small atom as hydrogen is not expected to penetrate through graphene's dense electronic cloud within billions of y…
Accurate determination of electron-hole asymmetry and next-nearest neighbor hopping in graphene
A. Kretinin, G. L. Yu, R. Jalil +7
The next-nearest neighbor hopping term t' determines a magnitude and, hence, importance of several phenomena in graphene, which include self-doping due to broken bonds and the Klei…
