All of our products at Grolltex are fabricated and packaged in a Class 1000 cleanroom. Adhering to our strict procedures and processes allows us to achieve high-yield, high-quality CVD graphene and hexagonal Boron Nitride (hBN) production, resulting in exceptional graphene monolayer material quality at an affordable price. Every batch of graphene and hBN is analyzed meticulously and comes with a datasheet unique to your specific batch of graphene, so that the customer always knows the metrics that are most important to them. The individual specification sheet provided for each unit of graphene or hBN sold by Grolltex contains optical images of graphene from the batch transferred onto Si/SiO2, FET mobility on Si/SiO2, sheet resistance, and Raman spectra. We are happy to provide the batch-specific sampling spectra txt/scv files to our customers upon request. Each graphene or hBN sheet is vacuum sealed in a clean and inert nitrogen environment. Secondary packaging of our graphene material under positive nitrogen atmosphere in a moisture-proof, light-proof, static-proof cleanroom bag ensures prolonged shelf-life when not in use by the customer.
Graphene’, the word taken from the graphite that the material was originally isolated from, is an extremely electrically conductive form of elemental carbon that is composed of a single flat sheet of carbon atoms arranged in a repeating hexagonal lattice.
Graphene is one million times thinner than paper. And being made from carbon, it is one of the most available materials on earth. Graphene’s flat honeycomb pattern grants it many unusual characteristics, including the status of “strongest material in the world”. Columbia University mechanical engineering professor James Hone, once said it is “so strong it would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap”.
Graphene was isolated from the lead of a pencil and identified in 2004 by two scientists at the University of Manchester, Drs. Geim and Novoselov. Their discovery, and research on the resulting material breakthrough, earned them the Nobel prize in 2010. Since then there have been over 15,000 patents issued worldwide for products and applications involving graphene.
