Graphene Material Discoveries

Researching two-dimensional materials and their heterostructures, offers the potential for amazing scientific discoveries and the promise of real-world uses that does not require new tooling.
Graphene is lightweight, stiff, and strong. In fact, it’s one of the strongest materials known to man. Graphene properties have many uses including making incredibly strong composite materials such as mixing graphene with plastics that have incredible strength per unit of mass.

Graphene Coating on Silicon Wafers

We are investigating the use of graphene coating on silicon wafers to facilitate the absorption and conversion of light into photovoltaics in the next generation of silicon solar cells. Ultimately, the efficiency of silicon PV cells could be up to 1300%. In order to coat the graphene coatings, they can be dissolved from the substrate with the help of a thin film of water.

Monolayer Graphene on Copper (Cu)

Growing monolayer graphene on Copper (Cu) thin films or Silicon (Si) Wafers works great for the production of massive direct graphene components. Researchers have demonstrated metal-based peeling processing the transfer of monolayers of graphene structures onto copper foil without destroying the base wafer.


Why copper foil? Cu is used for CVD growth because it enables production of large area single-layer graphene.

Graphene Oxide

Graphene oxide is one of the most popular 2D materials available and a fascinating nanomaterial that is huge. It is a widely dispersed solution that is bound to aqueous solvents and has useful properties and a wide range of applications in electronics, sensors and optics. Groups of water molecules move through hydrophilic solutions in this way. This forces flakes to form the outer layers of the fibre pack, creating a kind of skin.

Reduced Graphene Oxide (1 Gram)

reduced grapheneThe reduction of graphene oxide (simultaneous peeling or reduction of graphite oxide) is considered the most promising for the large-scale production of graphene and is referred to as reduced graphene oxide or RGO. RGO is a form of graphene with similar properties to graphene, but with good conductor properties. There are several ways to reduce RGO that are inexpensive and simple. It is popular and attractive as an effective and cost-effective method for those who want to manufacture graphene-related materials such as RGO. The reduction of graphene oxide has proven to be of high quality, as it is practically identical to untouched graphene.

A partial reduction can be achieved by treating suspended graphene oxide with Hydrozine Hydrazine for 24 hours at 100 degrees Celsius, by exposing it for a few seconds to hydrogen plasma or by exposing graphene oxide to strong light pulses like xenon flashes. Thermal reduction produces a higher degree of reduction than chemical processes, which leads to higher electrical conductivity. The RGO with strong reduction contains residual oxygen and structural defects caused by chemical oxidation and synthesis of the reducing agents and can be synthesized from inorganic substances such as NAB or organic substances such as phenylhydrazine hydrates and hydroxylamines.

Graphite oxide has aroused great interest as a possible way of producing and manipulating graphene, a material with exceptional electronic properties, on a large scale. Graphite oxide contains flakes or monolayers of several layers of graphene that are interspersed with water platelets and platelet interactions, depending on the carrier medium, thereby reducing surface functionality and improving hydrophilia. The associated high temperatures can lead to damage to individual flakes, a break-down of flakes and the introduction of defects in the structure.

The production of monolayer large area graphene and wrinkle-free multilayer graphene films, which are transferred to glass substrates, is carried out with graphene sheets, as shown in Fig. High-quality graphene foil monolayers are applied to copper foil by means of chemical vapour deposition (CVD). Similar to other graphene foil products, including single layer graphene foils (Figure 3) manufactured using CVD deposits on round substrates, PET measures a thickness of 1.75 mm during the wet transfer process.  Show Source Texts

Based on the CVD method, many large-format monolayer graphs can be produced by fixing and transferring the multi-layer graphene film onto the TI adhesive layer. Figure 4 shows schematic structure of the graphene monolayers prepared and multilayers of graphene foils transferred to the TI glass substrate. Raman spectra of the bare top of graphene were observed when it was detached from the substrate and attached to graphene foil after transfer to the substrate. We assume that the interacting oxygen in the substrate forms a strong O-chemical bond, taking advantage of the concept of transferring wrinkle-free graphene films to different functional substrates by introducing a TI adhesive layer. With this method, high-quality graphene products can be synthesized, resulting in monlayer-graphene coverage of up to 90%.

Monolayer Graphene on Quartz (10mm x 10mm Wafer)

monolayer graphene on pet 10mm x 10mmThe researchers used a single layer of graphene with a copper catalyst that was grown using the chemical vapour separation method (CVD) and transferred using the chemical etching method to a dielectric substrate (quartz). The growth rate and quality of graphene on quartz substrates showed a remarkable improvement over the conventional CVD process. In TA, BOAT and CU-optimized CVD reactors, SEM images of graphene films at different magnifications transferred to Si-SIO-2 substrate (C) have been delivered to the CU-optimized VDC Rifles at various magnifications. Our single-layer graphene-quartz lid is made by VTD transfer on a circular base of 500 mm thick quartz with wet transfer. Graphene was deposited on the quartz substrate.

This situation was confirmed by the investigation of CVD graphene growing in our aging quartz tubes (Figure S3), where SiO2 particles proved to be secondary in the graphene domain, highlighting their role as the preferred additional nucleus. Figure 1 SEM image of contaminated graphene film grown in CVD quartz tubes with copper transfer (Si / SiO 2 at 300 nm C. ) was used to prepare a high quality, uniform single-layer graphene plate with a growth time of 60 seconds using a generic recipe to saturate a Cu substrate with graphene focusing on Cu foil.

Layers of PECVD thickness were used to grow graphene films on quartz. Using THZ-TDS measurements, we examined surface boundary conditions of Mg samples deposited in a molten quartz substrate on both the substrate and in the air to achieve a complex refractive index and electrical conductivity of graphene.

Suspended Monolayer Graphene on TEM Grids (Quantifoil Gold) Pack 4 units

suspended monolayer graphene-on-tem gridsThe first image of Transmission Electron Microscopy (TEM) images of thin graphite samples consisting of a few graphene layers was released by G. Ruess and F. Vogt in 1948. The method of graphene crumpling by adding nanoscale folds to the graphite sample was achieved by applying a layer of graphene oxide on the shrunken film, shrinking and dissolving it. A clean monocrystalline graphene foil was grown in a commercially available copper foil (Alfa Aesar 46365, 25 mm thick) in a low pressure CVD tube furnace (LPCVD) system.

Monolayer Graphene on Cu with PMMA Coating (100mm)

100mm monolayer graphene on copper pmmaThe process described here leads to a high yield of suspended, clean graphene films on perforated carbon ribs. In order to etch the copper, graphene is protected by a rich layer of Polymethyl Methacrylate (PMMA). In a modified tube furnace the carbon source and copper matrix are heat independent and the temperature zones and process parameters (growth time and growth temperature) are regulated to control the growth of the graphene film on the copper substrate, which is controlled by low pressure. On the surface of the copper foil form a single layer of graphene film at a growth temperature of 800 degrees Celsius and two layers of graphene film at 600 degrees Celsius and 700 degrees Celsius. After the film is gone, we can transfer the graphene films with PMMA for a distance of 10 minutes into deionized water, or you can transfer the water and wait for up to 20 minutes.
