suspended CVD graphene
Group visit to EMPA
The group had the pleasure to visit the lab of Prof. Dr. Michel Calame today (5. April 2019) at EMPA Thanks a lot Michel for this interesting day!
Lujun won the Poster Award. Congratulations!
Lujun won the Poster Award at the IWEPNM 2019 Kirchberg meeting. Congratulations!
A super superlattice in encapsulated graphene
Our paper entitled “New Generation of Moiré Superlattices in Doubly Aligned hBN/ Graphene/hBN Heterostructures” appeared in Nano Letters. Two incommensurate lattices in contact generate a Moiré superlattice. This happens for the pair hBN-G (hexagonal boron nitride-graphene). Take encapsulated graphene hBN-G-hBN.
Group ski excursion to Elm
Wonderful weather: blue sky, sunshine and snow! We stayed overnight in the Berghotel Bischofalp We can highly recommend it. We all enjoyed the two days including Joost, who had to suffer a bit (see his right hand on the picture below):
An eye on carrier distribution in graphene with the help of a superconductor
Editors’ Suggestion Simon Zihlmann et al. “Nonequilibrium properties of graphene probed by superconducting tunnel spectroscopy”, Phys. Rev. B 99, 075419 (2019) In a conductor the current is carried by electrons. In a macroscopic conductor, the charge distribution is in local equilibrium,
Paper on spin injection into graphene by spin pumping using FMR
Wideband and On-Chip Excitation for Dynamical Spin Injection into Graphene Graphene is an ideal material for spin transport, as very long spin-relaxation times and lengths can be achieved even at room temperature. However, electrical spin injection is challenging due to
Group Excursion “crossing the Röstigraben”
On 16th and 17th of August we went on our Summer group excursion. This time to the pre-alp region of Fribourg in the area of Gruyère, chosen by Raphaelle likely because of the top reputation for cheese (and chocolate ?).
Masterwork on Quantum Transport in Nanowire-Superconductor Hybrid Devices
Masterwork on Quantum Transport in Superconductor Hybrids based on Nanowires The current project is strongly motivated by the recent excitement about topological phases and Majorana bound states that can appear in hybrid devices in low dimensions, for example in semiconducting
Master project available!
Two master’s project are available on (a) topological insulators and superconductors by design using 2D van der Waals heterostructures, see Master on Engineered Topological Insulators and (b) quantum transport in nanowire-superconductor hybrid devices, see Quantum-Transport in Nanowire Hybrids
3rd graphene workshop in Basel
3rd Graphene workshop 21-22 June, 2018 This year we had organized the graphene workshop for the 3rd time, which again was really successful, with interesting talks from all over Europe. See you next year! Some impressions: The program: Thursday
