Graphenea is a private European company (based in Spain) focused on the production of high quality graphene for industrial applications. The company produces single-layer graphene sheets, bi-layer graphene, multi-layer graphene, graphene oxide and other materials - on any substrate the customer provides.
In November 2012 the company launched an online store. In 2015, the company announced plans to construct a new graphene pilot plant in a $2.5 million investment.
The latest graphene news from Graphenea:
Graphenea recently launched a graphene foundry service – GFAB. The company will manufacture custom circuit designs on graphene wafers up to 6”. The service is aimed at enabling fast device prototyping and accelerating development of new applications, lowering entry barriers to graphene-based solutions.
Graphenea states that in view of the market demands, the offer now includes small batch sizes (1-3 wafers). Lithography masks can be manufactured by Graphenea or provided by the customer. GFAB includes graphene growth, transfer on 4” and 6” wafers, metal contact deposition and lift-off, and graphene lithography with etching.
The Graphene-Info team attended this year's Graphene Week, organized by the Graphene Flagship in San Sebastian, Spain, 10-14 September 2018. The event attracted over 600 visitors from all over the world, and was extremely well organized.
While the talks and lectures were clearly scientifically-oriented, the commercial angle was also evident and many institutes and companies were there to show their recent product advancements. The Graphene Flagship's booth held a fascinating array of exhibits: graphene-enhanced retina and neural prosthesis (biomedical devices) by the ICN2 as a part of Braincom, Airbus' graphene composite for the leading edge of the tail of the Airbus A350, Nokia, Ericsson and AMO's graphene-based modulators and photodetectors for optical communications, a prosthetic robotic hand enhanced with graphene nerve sensors by the IIT, University of Cambridge's insole graphene-based pressure sensor and more.
MIT and Graphenea have developed an array of graphene sensors for sensitive and selective detection of ammonia. The array consists of 160 graphene pixels, allowing large statistics that result in improved sensing performance. The sensors are extensively tested for various real-life operational conditions, which seems to be a step forward to practical use.
The sensors are built by attaching porphyrins, a class of organic molecules, to the graphene surface. Porphyrins are particularly well-matched to graphene sensors because they provide excellent sensitivity while producing minimal perturbation to graphene’s outstanding electrical properties. When ammonia molecules attach to porphyrins, the compound becomes a strong dipole that changes electrical properties of the graphene. This electrical change is detected as a sign of the presence of ammonia.
Graphenea, in collaboration with industrial and academic partners (Infineon Technologies, WITec, RWTH Aachen University and Simune Atomistics), announced the successful completion of project NanoGraM that focused on nano/microelectromechanical (NEMS/MEMS) devices based on graphene. The project focused on three specific device concepts for potential future products: graphene microphones, graphene-membrane pressure sensors and graphene-membrane Hall sensors.
The target markets for these devices include portable electronics (smartphones, laptops), automotive, industrial, and smart homes, among others.
Graphenea has launched sales of GFETs (graphene field effect transistors) aimed at lowering barriers to adoption of graphene, especially the sensors market. Researchers needing GFETs for their applications, whether in gas, biosensing, or other applications, can now purhcase high-quality GFET devices.
Graphenea has started by launching two standard GFET-for-sensing configurations called GFET-S10 and GFET-S20, each including 36 individual GFETs on a one square centimeter die, but differing in device layout. The GFET-S10 has devices distributed evenly over the die and the GFET-S20 has the devices concentrated in the center of the die with electrical pads located at the die edge. The GFET-S20 devices all have a 2-probe geometry for probing electrical properties during sensing, whereas the GFET-S10 houses 30 devices with the Hall bar geometry and 6 with 2-probe geometry. The Hall bars enable magnetic field sensing, apart from applications in graphene device research, bioelectronics, biosensing, chemical sensing, and photodetectors that the 2-probe geometry also allows.
