Introduction by the chairman

Marcel Hoek, NWO, The developments in the Graphene Flagship

After an initial ramp-up phase,  the Graphene Flagship is now at full speed. With its goal of bringing graphene to the European market, it is moving toward higher technology readiness levels, while maintaining a strong fundamental science component. In addition to the science and technology roadmap of 2015, the flagship is now developing a technology and innovation roadmap to be published in 2017. This introduction will cover the outline of the roadmaps and the involvement of NWO in graphene research and the Graphene Flagship, in particular through our involvement in FLAG-ERA, the Flagship ERA-NET.

Seeing graphene grow

Prof.dr. Joost W.M. Frenken, director, Advanced Research Center for Nanolithography (ARCNL)

Scanning tunneling microscopy is used routinely to image graphene with atomic resolution. This talk will demonstrate that STM can also be used to follow the growth of graphene on metal surfaces. We have developed an STM setup with extreme thermal stability. This instrument enables us to investigate the chemical vapor deposition (CVD) of graphene at realistic process temperatures, e.g. 1000°C. Our images and movies show in detail how the graphene grows on Rh(111) and Ir(111) surfaces and how the nucleation-and-growth history determine the quality of the resulting graphene monolayers.

Transfer-free graphene ready for the production of sensors

Dr. ir. Sten Vollebregt, assistant professor, Department of Microelectronics, Delft University of Technology

Wafer-scale graphene is typically deposited using a CVD process on a metal catalyst. For practical use, the graphene has to be taken from this catalyst and transferred to a device wafer. As graphene is extremely thin this is not a straightforward job, hence transfer is seen as one of the biggest bottlenecks for commercial use of graphene in micro-electronics. We developed a transfer-free method as alternative to the complicated transfer process, and used it to demonstrate wafer-scale fabrication of graphene devices. Using this process, we are currently investigating graphene for the use in different environmental sensors.

Solution-processed flexible graphene conductors and devices

Dr. Heiner Friedrich, Assistant Professor, Department of Chemical Engineering and Chemistry, Eindhoven University of Technology

Graphene-based conductors have a high potential for application in flexible electronics due to their good electrical conductivity combined with high mechanical strength, bendability, chemical inertness and ease of recycling. This talk summarizes our research into environmentally friendly approaches for the solution processing of graphite into graphene inks followed by industrially relevant deposition and patterning techniques. Aiming at high volume applications, processing proceeds via graphite intercalation, thermal exfoliation, ink formulation, deposition by inkjet or screen printing to realize, e.g. radio frequency identification devices and wideband antennae’s. These device structures can be deposited on a wide range of substrates including paper or polymer foils and expose virtually no bending fatigue.

The use of pyrolitic graphite for spacecraft thermal control

Alexander Maas, Thermal Engineer , Airbus Defence and Space

With a twenty times higher thermal conductivity per unit mass than aluminum, pyrolytic graphite offers great potential in the application to spacecraft thermal control systems. Over the last years, Airbus DS NL has been developing thermal control applications for this material. The combination of lightweight and high thermal conductivity allows for an independent optimization of thermal performance. In 2016, first flight hardware was qualified and delivered. This presentation gives an overview of the HiPeR developments and presents the current design status and challenges for HiPeR flexlinks, radiators, and doublers.
