High quality Graphene producer - Graphenea is a leading graphene company. We manufacture and supply graphene products and materials for your industrial and research needs. Graphene Foundry.

Their Products:

Graphene on Your Substrate - This is a tailor made graphene product. You send your substrate to our laboratory (including your order ID and your email address as a reference) and we then use our innovative method to transfer the graphene monolayer on top of it and send it to the address you specify. Examples of substrates we have successfully transferred graphene to: devices, solar cells, LEDs, gold, alumina, silver mirrors and sapphire.
Easy Transfer: Monolayer Graphene on Polymer Film - the easiest way to transfer monolayer graphene onto your substrate. We applied our long experience in growing and transferring high quality graphene films to let you experiment with any novel substrate by using Graphenea’s Easy Transfer.
Monolayer Graphene on Cu - This product consist on a single-layer graphene grown on copper foil substrate.
Monolayer Graphene on 90 nm SiO₂/Si - Our monolayer graphene on SiO₂/Si (fully covered) is a bidimensional material produced by CVD and transferred to a circular substrate of SiO₂/Si (90nm) by a wet transfer process. We consider it to be a benchmark product in the graphene market - not only for its excellent quality, but also for its shape, size and number of applications.
Graphene Oxide Water Dispersion (0.4 wt% Concentration) - Our graphene oxide is noted for its mechanical and thermal properties. The raw material - graphite - is chemically processed to obtain monolayer flakes of graphene oxide.
Highly Concentrated Graphene Oxide (2.5 wt% Concentration)
Graphene Oxide Powder
GFET for Sensing applications - The GFET-S10 chip from Graphenea provides 36 graphene devices distributed in a grid pattern on the chip.  Thirty devices have a Hall-bar geometry and six have a 2-probe geometry.  The Hall-bar devices can be used for Hall-bar measurements as well as 4-probe and 2-probe devices.  There are varying graphene channel dimensions to allow investigation of geometry dependence on device properties.
GFET-S20 (Die size 10 mm x 10 mm) - Processed in Clean Room Class 1000 - The GFET S-20 chip from Graphenea is designed for measurements in liquid medium. The new version provides 12 graphene devices, with encapsulation on the metal pads to avoid degradation and reduce leakage currents, and the probe pads located near the periphery of the chip. It also includes a non-encapsulated electrode at the center of the chip, which allows liquid gating without the need of an external gate electrode.
Suspended Graphene on TEM Grids (Quantifoil Gold) - Pack 4 units - The monolayer graphene is grown by CVD and transferred onto a Quantifoil TEM grid. The graphene is suspended over 2μm holes.

One of the most tedious processes in supplying the researchers with affordable substrates is quoting. In fact, it is so time consuming that most wafer supply firms won’t even quote a job for a small run, never-mind a single wafer.

Most researchers have experienced being ignored. They send a request, then they wait for the quote that never comes. They then send a follow-up email. And they wait some more. Finally the researcher makes the phone call. When the researcher tells the wafer vendor that they just want one wafer they are either hung-up on or provided with a ridiculously high quote and long lead-items.

But there is hope!

UniversityWafer, Inc. was created to cater to the researcher who wants small quantities and short lead-times. Our professional staff is trained to handle even the most difficult low volume requests and we pride ourselves on fast responses and turnaround.

Why buy in volume if you don't have to?!
