STM observation of a box-shaped graphene nanostructure appeared after mechanical cleavage of pyrolytic graphite

A description is given of a three-dimensional box-shaped graphene (BSG) nanostructure formed/uncovered by mechanical cleavage of highly oriented pyrolytic graphite (HOPG). The discovered

Large and flat graphene flakes produced by epoxy bonding and reverse exfoliation of highly oriented pyrolytic graphite

TLDR
A fabrication method based on substrate bonding of a thick sample of highly oriented pyrolytic graphite (HOPG), followed by its controlled exfoliation down to the few to single graphene atomic layers opens the way for deposition of graphene on any substrates, including flexible ones.

Large-scale pattern growth of graphene films for stretchable transparent electrodes

TLDR
The direct synthesis of large-scale graphene films using chemical vapour deposition on thin nickel layers is reported, and two different methods of patterning the films and transferring them to arbitrary substrates are presented, implying that the quality of graphene grown by chemical vapours is as high as mechanically cleaved graphene.

The origin of wrinkles on transferred graphene

AbstractWhen two-dimensional graphene is exfoliated from three-dimensional highly oriented pyrolytic graphite (HOPG), ripples or corrugations always exist due to the intrinsic thermal fluctuations.

Frictional behavior of highly oriented pyrolytic graphite

Friction of a freshly cleaved highly oriented pyrolytic graphite (HOPG) surface and a roughened graphite surface against a silicon nitride tip is measured using a friction force microscope. The

Molecular beam epitaxial growth of graphene and ridge-structure networks of graphene

By gas-source molecular beam epitaxy (MBE) using cracked ethanol, we grew graphene at substrate temperatures between 600 and 915 °C on graphene formed on SiC(0 0 0 1) by thermal decomposition. To

Epitaxial graphene on ruthenium.

TLDR
It is shown that epitaxy on Ru(0001) produces arrays of macroscopic single-crystalline graphene domains in a controlled, layer-by-layer fashion, and demonstrates a route towards rational graphene synthesis on transition-metal templates for applications in electronics, sensing or catalysis.

Characterization of nanomechanical graphene drum structures

Characterization of nanomechanical graphene drum structures is presented in this paper. The structures were fabricated by mechanical exfoliation of graphite onto pre-etched circular trenches in

A review and outlook for an anomaly of scanning tunnelling microscopy (STM): superlattices on graphite

Since its invention in 1981, scanning tunnelling microscopy (STM) is well-known for its supreme imaging resolution enabling one to observe atomic-scale structures, which has led to the flourishing of

The structure of suspended graphene sheets

TLDR
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.
