Alexander Rothstein just returned from a 3 weeks visit of the Quantum Nanoelectronics Group of Prof. Pablo Jarillo-Herrero at the Massachusetts Institute of Technology (MIT) in Boston (USA) for kicking-off a joined collaboration and for learning more about the fabrication of making large twisted bilayer graphene. Our 2D Materials and Quantum Devices Group at the RWTH thanks Dr. Aviram Uri (left) und Liqiao Xia (right) for sharing their knowledge.
