Although graphite is known as one of the most chemically inert materials, we have found that graphene, a single atomic plane of graphite, can react with atomic hydrogen, which transforms this highly conductive zero-overlap semimetal into an insulator. Transmission electron microscopy reveals that the obtained graphene derivative (graphane) is crystalline and retains the hexagonal lattice, but its period becomes markedly shorter than that of graphene. The reaction with hydrogen is reversible, so… 

Size- and shape-dependence of the graphene to graphane transformation in the absence of hydrogen

Graphene is a fascinating material with many unique properties, some of which have lead to the development of basic circuit elements with atomic level precision. However, large area, pristine

Controlled hydrogenation of graphene sheets and nanoribbons.

A comparison of Raman spectrum and conductivity data of partially hydrogenated monolayer and bilayer graphene suggests that the latter is also quite susceptible to adsorption of hydrogen atoms, despite a stiffer lattice structure.

DFT investigations of the hydrogenation effect on silicene/graphene hybrids

Calculations reveal that pure SG is a non-zero band gap semi-conductor with stable planar honeycomb structure, which opens a wide spectrum of possibilities for designing SG-based nanodevices with controlled and tuned properties.

Adsorption of monovalent metal atoms on graphene: a theoretical approach

This work investigates, using first-principles calculations, electronic and structural properties of hydrogen, lithium, sodium, potassium and rubidium that are adsorbed, in a regular pattern, on a graphene surface, and shows the possible stability of such ad-graphene layers.

Graphene hydrate: theoretical prediction of a new insulating form of graphene

Using first-principles calculations, we show that the formation of carbohydrates directly from carbon and water is energetically favored when graphene is subjected to an unequal chemical environment

Hydrogenation of Graphene by Reaction at High Pressure and High Temperature.

Graphene is heated in molecular hydrogen under compression to modest high pressure in a diamond anvil cell and a method whereby fully hydrogenated graphane may be synthesized for the first time is proposed.

A trigonal planar network in hydrogenated epitaxial graphene: a ferromagnetic semiconductor

Hydrogenated epitaxial graphene has distinctive electronic properties compared to the two-sided hydrogenated graphene referred to as graphane. Of particular interest is the experimentally observed

Hydrogen uptake by graphene and nucleation of graphane

Reactions of hydrogen with electronic materials are important for the operation of related devices. Here we use first-principles density-functional theory calculations to describe hydrogen reactions

Stacks of graphene with silicane or germanane: a first-principles study

We report the results of density-functional theory calculations on the stability and properties of hybrid layered systems composed of graphene and silicane or germanane monolayers. We find that the



Molecular doping of graphene.

This letter presents the first joint experimental and theoretical investigation of adsorbate-induced doping of graphene, and shows that this peculiar density of states (DOS) of graphene is ideal for "chemical sensor" applications and explains the recently observed NO2 single molecule detection.

Hydrogen on graphene: Electronic structure, total energy, structural distortions and magnetism from first-principles calculations

Density-functional calculations of electronic structure, total energy, structural distortions, and magnetism for hydrogenated single-layer, bilayer, and multilayer graphenes are performed. It is

The structure of suspended graphene sheets

These studies by transmission electron microscopy reveal that individual graphene sheets freely suspended on a microfabricated scaffold in vacuum or air are not perfectly flat: they exhibit intrinsic microscopic roughening such that the surface normal varies by several degrees and out-of-plane deformations reach 1 nm.

The bottom-up chemical approach of tuning the graphene sheet properties provides a path to a broad new class of graphene-based materials and their use in a variety of applications.

Electronic transport properties of individual chemically reduced graphene oxide sheets.

Comparison of multilayered sheets revealed that the conductivity of the undermost layer is reduced by a factor of more than 2 as a consequence of the interaction with the Si/SiO2 substrate.

Electric conductivity measurements indicate a 10000-fold increase in conductivity after chemical reduction to graphene, and temperature-dependent conductivity indicates that the graphene-like sheets exhibit semiconducting behavior.
