AMO was part of the EU Graphene Flagship delegation at the Tallinn Digital Summit on September 29, 2017, where research results and key technological advances enabled by graphene and related materials were explained to European Heads of State and Government.
The Tallinn Digital Summit, held under the Estonian presidency of the Council of the European Union, is a platform for Heads of State and Government from across Europe to launch high-level discussions on digital innovation with the aim of keeping Europe ahead of the technological curve while becoming a global digital leader in the next years. The participants focussed on trends and technologies likely to emerge in the next ten years and their impact on crucial areas of security, e-government, industry, economy and society. Academic and industrial co-exhibitors from across the Graphene Flagship consortium presented many different demonstrators to illustrate the potential of graphene and related materials in Europe’s path to global digital leadership.
The presences of the EU Graphene Flagship project was a unique opportunity and a great honour at the same time to show the highest decision makers what Europe can achieve by working together towards a common goal, and demonstrates that the Flagship is well on its way to realize its ambitious goals.
Professor Max Lemme, Director of AMO GmbH and Chair of Electronic Devices at RWTH Aachen University, had the opportunity to explain many of the latest Graphene Flagship achievements to the visitors, including several Europen Heads of State and Government. “Graphene is a very exciting material and we are moving our research towards higher technology levels. This is where innovation happens, and we are confident to enable new applications in (opto-)electronics and sensorics with graphene and 2D materials.” stated Professor Lemme.
The Graphene Flagship exhibition area showcased the work of academic and industrial co-exhibitors from across the consortium on five application areas: sensors and the Internet of Things, devices for the digital world, society and healthcare, energy and solar cells, and composites. The exhibit at the Tallinn Digital Summit allowed the Graphene Flagship to show the important part Graphene will play in technological innovation for our digital future.

Graphene and related materials are ideal for optoelectronic components in integrated photonic devices, to be used in the next generation of communications systems. Chip-integrated electro-optic devices can significantly increase the performance of datalinks in terms of capacity, lower energy consumption and costs.
In cooperation with RWTH Aachen University and the University of Pisa, researchers from AMO realized the world first microwave power detector based on metal-insulator-graphene (MIG) diodes, which is able to perform power detection for frequency up to 50 GHz.
Diodes are key components for RF electronic devices, which are typically used at radio frequencies for signal reception, frequency multiplication, or energy harvesting applications. In recent years thin film technology based diodes, for example metal-insulator-metal (MIM) or MIG diodes, attract increasing interest because of their excellent performance along with the low series resistance which is a crucial benefit for high frequency operation. Such thin film diodes are already used in display applications and the thin film technology enables an unrestrained choice on the target application substrate, such as flexible foil.
The MIG diodes presented in this work were fabricated at AMO using a thin film technology platform with CVD grown graphene and TiO2 deposited by atomic layer deposition. The MIG diodes show excellent static figures of merit significantly outperforming conventional MIMs. RF power detection based on the MIG diode is for the first time demonstrated in this work, showing a linear detection responsivity of 2.8 V/W at 2.4 GHz and 1.1 V/W at 50 GHz. These excellent DC and RF performance parameters make MIG diodes very promising for future application in thin-film technology and for 5G.
The work leading to these results was financially supported by the European Commission under the projects Graphene Flagship and SPINOGRAPH, and by the German Science Foundation (DFG) within the priority program 1796 FFlexCom.

The Graphene Flagship and ICFO, with support from the GSMA, present the Graphene Experience Zone at the 2017 Mobile World Congress (MWC). MWC is the world’s largest gathering for the mobile industry, (with over 100,000 attendees), and will be held from 27 February to 2 March 2017 in Barcelona. The Graphene Experience Zone will showcase the latest achievements and innovations from the graphene community in an interactive and accessible way. AMO andRWTH Aachen University will present an on-stage demonstration of a graphene based Wifi receiver within their Graphene flagship cooperation.
Following the success of the Graphene Pavilion at Mobile World Congress 2016 and Mobile World Congress Shanghai 2016, graphene is back at MWC 2017 with an immersive Experience Zone exploring graphene mobile innovation. The Graphene Experience Zone contains industry and academic co-exhibitors who will highlight current graphene innovation in mobile applications ranging from smart composites to wearable sensors, all using demonstrators and operational prototypes to bring graphene to life.
ICREA Professor Frank Koppens from ICFO – The Institute of Photonic Sciences in Barcelona, who is Scientific Chair of the Graphene Experience Zone, comments “The Graphene Pavilion at MWC 2016 generated tremendous excitement and it has become a prominent element of the event in a relatively short time. The Graphene Experience Zone at Mobile World Congress 2017 will be the place to showcase future graphene technologies at work, presenting even more demonstrators and a spectacular design of the interactive zone.”
This year the Graphene Experience Zone will feature five different innovation areas: IoT and Sensors; Wearables and Health; Energy; Datacoms; and Composites. Each area will contain specialised demonstrators and prototypes developed by leading industry and academic partners. At the heart of the Graphene Experience Zone will be the graphene concept car, developed by the University of Manchester in collaboration with Haydale, UK, and British carmaker BAC (Briggs Automotive Company). The car, which combines many of these different technological areas, will be showcased in a truly captivating setting.

This event is run as part of the Graphene Flagship and developed by ICFO – The Institute of Photonic Sciences, Istituto Italiano di Tecnologia (IIT), Novalia and University of Cambridge with the support of the European Commission and the GSMA.
With graphene helping to develop the mobile industry of the future, you cannot afford to miss the Graphene Experience Zone at Mobile World Congress 2017.
Graphene and the Mobile Industry
Graphene is one of the most interesting and versatile materials known to date. The world’s first two dimensional material, this single layer of carbon atoms arranged in a hexagonal lattice has a set of unique and outstanding properties. As well as being the thinnest, strongest and lightest material, graphene is flexible, impermeable to molecules and extremely electrically and thermally conductive. As the world strives to maintain its pace of innovation, graphene has much to offer. Graphene is helping to facilitate the next generation of technology: from interconnects for data communication to screens and casings. For example, the strong and flexible nature of graphene makes flexible displays and bendable batteries possible. Its excellent sensing ability can be used in the next generation of wearable electronics and to develop building blocks for the internet of things. Graphene’s unique combination of properties coupled with its ease of incorporation into composite materials mean that it can enhance the composite world. Graphene is also paving the way for novel diagnosis and treatments such as in the realm of drug delivery and biosensors. Graphene-based technologies are proving integral to the new generation of communications, such as 5G, enabling high performance optical communication systems through ultra-fast and compact optoelectronic devices.
