Graphene monolayer film consists of an atomically-thin layer of carbon atoms that are arranged in a hexagonal honeycomb lattice. It was first isolated via mechanical exfoliation - the Scotch-tape method. Chemical vapour deposition (CVD) and epitaxial methods were later developed and commonly used as alternative methods for growing research-grade single, bilayer and few-layer graphene films.

High-quality graphene monolayer film is available on three different substrates: SiO₂/Si, PET (polyethylene terephthalate), and copper foil. Different sizes and substrate types of monolayer graphene films are also available via custom request (see list below).

• Glass (1 cm × 1 cm, 1 cm × 2 cm, 2 cm × 2 cm or custom-made sizes)
• Sapphire (1 cm × 1 cm, 1 cm × 2 cm, 2 cm × 2 cm or custom-made sizes)
• Nickel (1 cm × 1 cm, 1 cm × 2 cm, 2 cm × 2 cm or custom-made sizes)
• Silicon (1 cm × 1 cm, 1 cm × 2 cm, 2 cm × 2 cm or custom-made sizes)
• Quartz (1 cm × 1 cm, 1 cm × 2 cm, 2 cm × 2 cm or custom-made sizes)

Applications

With a unique combination of novel electronic, optical, and mechanical properties, graphene-based nanomaterials have applications in energy generation and storage. For example, they can applied in photovoltaic devices and batteries, sensors and flexible electronics, photodetectors, and biomedical applications (e.g. drug delivery, bio-imaging, and tissue engineering).

Synthesis

High-quality monolayer graphene films were first grown directly on copper foil via the chemical vapour deposition (CVD) method. The films were later transferred to the desired substrates via the wet chemical graphene-transfer process.

Usage

Monolayer graphene films are ready to use in various research purposes, such as microscopic analysis, photoluminescence and Raman spectroscopy studies. Graphene monolayer films can also be transferred to other substrates.
