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.Continue reading “A scalable manufacturing-technology for highly sensitive photodetectors on flexible substrates”
Banszerus and coworkers have reported the first experimental observation of the spin-orbit gap in bilayer graphene.Continue reading “First observation of the (tunable) spin-orbit gap in bilayer graphene”
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.Continue reading “The fundamental mechanisms that underpin CVD technology for atomically-thin 2D films — a talk by Prof. Stephan Hofmann (Cambridge University)”
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.
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
With what could be a step forward towards large-scale high-performance graphene electronics, a team of German and French scientists has demonstrated the excellent quality of monoisotopic hexagonal boron nitride grown at atmospheric pressure by the group of James Edgar at Kansas State University.Continue reading “The excellent quality of boron-nitride grown at atmospheric pressure”
Max Lemme is the protagonist of a short video produced by Arte for series Verknüpft (Linked). Using a simple language, the video explores the connection between a common pencil and a self-driving car. That connection is graphene – or better nanotechnology based on graphene, like the one developed by Lemme’s group at AMO and RWTH.Continue reading “Graphene on Arte”
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.Continue reading “Graphene on the radio”
Researchers from RWTH Aachen University, AMO GmbH, Stanford University and IHP have demonstrated that heterostructures formed by silicon, molybdenum disulfide (MoS2) and graphene are potential candidates as emitter-diodes of graphene-base hot-electron transistors.Continue reading “An efficient emitter for graphene-base hot electron transistors”
The Aachen Graphene & 2D Materials Center has won two projects on basic research and innovation on graphene in the last FLAG-ERA Joint Transnational Call.Continue reading “Two new FLAG-ERA projects in Aachen”
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.Continue reading “How to make graphene (and 5000+ related materials)”
