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.
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):
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,
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
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 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
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 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
Parafermion project started! The QuantEra project entitled “Topologically protected states in double nanowire superconductor hybrids” started with a kick-off meeting on April 4 in Basel. Coordinator: Szabolcs Csonka (Budapest University of Technology and Economics, HU) Jesper Nygard (University of Copenhagen,
Congratulations to Cezar Harabula who defended his thesis entitled Lumped Impedance Matchers and GHz Noise Investigation of Quantum Dots last week on April 26th
