A scalable manufacturing-technology for highly sensitive photodetectors on flexible substrates

Researchers from AMO GmbH and RWTH Aachen University have successfully demonstrated high-responsivity molybdenum disulfide (MoS2) photodetectors on flexible substrates, realized with a scalable manufacturing technology. The work has been recently published in the journal ACS Photonics, and it is the result of a cooperation with the University of Siegen, Raith B.V., AIXTRON SE, and the University of Wuppertal.

The fundamental mechanisms that underpin CVD technology for atomically-thin 2D films — a talk by Prof. Stephan Hofmann (Cambridge University)

After a long break, the Aachen Graphene & 2D Materials Center resumes its series of seminars – now in a virtual form due to the current COVID-19 pandemics. The first guest will be Prof. Stephan Hofmann from the University of Cambridge, who will talk about the fundamental mechanisms that underpin CVD technology for atomically-thin 2D films.

Congratulations to Prof. Hiroo Suzuki

The Aachen Graphene & 2D Materials Center congratulates Hiroo Suzuki for his appointment as Assistant Professor at the Graduate School of Natural Science and Technology at Okayamy University in Japan.

Hiroo Suzuki

Dr. Suzuki came to Aachen in April 2018, as senior researcher in the Stampfer Lab (2nd Institute of Physics A) with an Overseas Research Fellowship from the “Japan Society for the Promotion of Science”. In Aachen, he worked on the transport properties of graphene and bilayer graphene constrictions and nanoribbons.

“I am very happy for Hiroo that he can return to Japan as Assistant Professor. A very nice success story and we wish him all the best for his future career”, says Prof. Christoph Stampfer

Graphene on the radio

On February 20, 2020, the radio station Deutschlandfunk Kultur has released a feature piece on “Graphene: the flat all-rounder”. Produced by the journalists Jennifer Rieger und Frank Kaspar, the piece offers an accessible overview of the unique properties of graphene, and a well-balanced analysis of the gap between the stellar expectations grown around this material and its current applications.

How to make graphene (and 5000+ related materials)

The Graphene Flagship has just released an extensive review article on the methods for producing and processing graphene and related materials. The article includes the knowledge of 70 co-authors and aims at being a single source of knowledge on graphene and related materials and a tool to facilitate their uptake in commercial applications.
