Researchers of RWTH Aachen University and AMO GmbH in collaboration with the Research Centre Jülich and the University of Siegen have investigated metal/molybdenum sulphide/silicon structures in order to understand the charge transport in such structures and to explore the possible potential of molybdenum sulphide to use as a dielectric in vertical heterostructured devices. The work was recently published in ACS Applied Nanomaterials (DOI: 10.1021/acsanm.8b01412).

Graphene hears the ultrasound
The research team led by Gerard Verbiest and Christoph Stampfer at the Physics Department at the RWTH Aachen University, discovered a new possibility for ultrasound detection. The physicists fabricated a graphene resonator on a silicon substrate in a way that the device could be mounted onto an ultrasound transducer. For the first time, this allowed them to measure the responds of a graphene resonator to ultrasound propagating through the substrate. They achieved a resolution of 7 pm/√Hz by making use of the unique properties of graphene. As the resolution solely depends on the electronic properties of the graphene, they show that the detection also works away from any mechanical resonance of the suspended graphene. The new insights could be very useful for numerous sensing applications at the nanoscale. The research results have now been published in the scientific journal “Nano Letters”.
Recent Publication
We have realized a valley flip for confined electrons in graphene quantum dots. It works by shifting the quantum dot a few nm across the superstructure of a graphene/h-BN stack (Nature Nanotechnology (2018).).
Novel Types of Quantum Bits
The research team of Professor Markus Morgenstern, chair of experimental physics (solid state physics) at RWTH Aachen University, discovered new possibilities for quantum electronics, with the support of colleagues from the Technical University of Vienna and the University of Manchester. The physicists combined two ultrathin materials, namely graphene and Boron-Nitride, in a way which makes it possible to switch individual electrons between two states. For the first time, this allowed them to invert the so-called valley degree of freedom of the electron. The new discovery could be useful for advanced information processing. The research results have now been published in the scientific journal ‟Nature Nanotechnology”.

Aachen Graphene & 2D Materials Center welcomes two new center members in 2018
Professor Joachim Knoch, Institute of Semiconductor Electronics as well as 
Professor Andrei Vescan, Institute of Compound Semiconductor Technology from RWTH Aachen University join as new members the Aachen Graphene & 2D Materials Center.
Prof. Vescan is a well-known expert for compound semiconductors, with a research focus on MOCVD material synthesis. He is currently working on the synthesis of different TMDCs. Prof. Knoch has a long experience on nano-scale semiconductor devices and works currently on new device concepts like tunneling transistors using 2D materials. These specific competences of the two new PIs are complementing and broadening the scope of the activities in the Aachen Graphene Center.
