Graphene

Where does graphene come from and why study it?

Graphene occupies a pivotal position in the realm of advanced materials, or 2D materials, playing a huge part in a new era of innovation and technological advancement.

Graphene is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, resembling a thin, but durable, sheet. While it occurs naturally in small quantities, most of the graphene used in research and applications is produced through various synthetic methods.

The ability to manipulate graphene at its atomic level creates endless possibilities in diverse fields. Graphene鈥檚 exceptional properties, including its strength, conductivity, flexibility, and thermal conductivity, are revolutionizing industries like electronics, energy storage, and biomedical applications.

Scientists are studying graphene to unlock its full potential and use it in advanced materials, which will help us make progress and innovate for a sustainable future.

Graphene application notes

Colocalized AFM-Raman Analysis of Graphene

Graphene, a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, exhibits remarkable electrical, thermal, and mechanical properties, making it a subject of extensive research in various scientific fields.

Colocalized AFM-Raman Analysis of 2D Materials Heterostructures

Van der Waals heterostructures, with their unique properties arising from the weak interlayer coupling and strong in-plane bonding, offer exciting opportunities for the design of novel materials with tailored electronic, optical, and mechanical properties.

TERS Characterization of Graphene Nanoribbons

This application note reports on the TERS nanocharacterization of graphene nanoribbons (GNRs) fabricated by electron beam lithography. The chemical nanoresolution achievable by TERS reveals the presence of amorphous carbon at the edge of the GNRs and locates organic residues. TERS can be considered as a valuable tool for characterizing nanopatterned graphene, an essential step for the development of graphene-based nano-devices.

Correlated TERS and KPFM of Graphene Oxide Flakes

AFM-Raman and its TERS mode are used to show nanoscale surface mapping of structural defects and chemical groups on graphene oxide (GO) flakes with 10 nm spatial resolution. The multi-parameter measurement methodology proposed in this note extends the capability of TERS allowing a direct correlation of local chemical composition and physical properties at the nanoscale not only for 2D materials but for almost any sample surface.

TERS Characterization of phospholipid bilayers and detection of nanoparticles

This application reports on TERS characterization of binary phospholipid bilayer systems deposited onto a gold coated coverslip. Such samples are used as model samples for directly and chemo-selectively visualizing the distribution of a lipid constituent at the nanometer scale.

The recent development of side-illuminated TERS analysis even provides the possibility to investigate the behavior of graphene-based structures under device operation.

Graphene oxide is a nanocarbon material with a high aspect ratio and a high surface area with a thickness of about 1 nm and a sheet length of several to tens of microns.
