Poster prize for Benedikt Frohn at the "Graphene Study 2019"
Benedikt Frohn won the 1st poster prize at the "Graphene Study 2018" in Obergurgl (Austria) with his poster on "Gate-defined electron-hole double dots in bilayer graphene". Congratulations! The 3rd poster prize went to Rebekka Garreis from the Ensslin group (ETH Zurich) with a very nice poster on charge detection in bilayer graphene quantum dots. Allowing one to conclude that soft-confinement in bilayer graphene is indeed highly promising.
ERC Consolidator Grant for Christoph Stampfer
For the second time Christoph Stampfer has been awarded a prestigious ERC Grant. After an ERC Starting Grant on “Graphene Quantum Electromechanical Systems” in 2011, he now receives a Consolidator Grant to work with his team on “2D Materials for Quantum Technologies”.

"56. ATG - Winterlauf" 2018
Our Institute participated successfully in the "56. ATG - Winterlauf" 2018. Despite the freezing cold temperatures and snow covered trails our colleagues put race numbers on and lined up with over 2500 other atheletes for the iconic 18,3 km long cross country run from Mulartshütte to Aachen. Alex (1:37:15), Markus (1:28:22) and Michael (1:14:10) as well as our very own Prof. em. Güntherodt (1:56:36) mastered the course and even had some energy left to smile for a finisher foto. Gratulations!
New Publication: Proximity-induced spin-orbit coupling in graphene/Bi1.5Sb0.5Te1.7Se1.3 heterostructures
Phys. Rev. B 98, 241402(R)(2018) The weak intrinsic spin-orbit coupling in graphene can be greatly enhanced by proximity coupling. Here, we report on the proximity-induced spin-orbit coupling in graphene transferred by hexagonal boron nitride (hBN) onto the topological insulator Bi1.5Sb0.5Te1.7Se1.3(BSTS) which was grown on a hBN substrate by vapor solid synthesis. Phase coherent transport measurements, revealing weak localization, allow us to extract the carrier density-dependent phase coherence length lφ. While lφ increases with increasing carrier density in the hBN/graphene/hBN reference sample, it decreases in graphene/BSTS due to the proximity coupling of BSTS to graphene. The latter behavior results from D'yakonov-Perel'-type spin scattering in graphene with a large proximity-induced spin-orbit coupling strength of at least 2.5 meV.
