General description

Be cautious not to drop
Keep away from contamination, heat, dust and flame etc.
Roll-to-roll, high-quality, monolayer CVD graphene with small grain size (∼5μm2) on silicon wafer, 4 inch diameter.


Our Roll-to-Roll CVD graphene products are true monolayer high quality graphene, fabricated inside a Cleanroom, heavily monitored and QC to assure high reproducibility.
The roll-to-roll process allows continuous, large scale graphene production.

This small grain size product is made by transferring roll-to-roll CVD graphene onto silicon wafer. It is ready-to-use with low sheet resistance, and would enable unmatched reproducibility and allow high performance for CVD graphene based cell culture scaffold, biosensors and chemically gated sensors.

Storage and Stability

Avoid direct sun light, avoid high temperature, avoid high humidity, and avoid dust.

Chemical vapor deposition (CVD) is considered to be an efficient method for fabricating large-area and high-quality graphene films due to its excellent controllability and scalability. Great efforts have been made to control the growth of graphene to achieve large domain


Dr. Xiang’s and Maruyama’s review presents the most recent research activities on 1D vdWHs, including the candidate materials, the synthetic techniques, and characterization methods. The optoelectronic applications are discussed in detail for different constructions of the 1D vdWHs-based devices (FETs, sensors, LEDs, photovoltaic devices, and light detection). Some challenges and perspectives for future development and applications of 1D vdWHs are also proposed to conclude the review.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
