Graphene, the first truly two-dimensional material isolated, is never perfectly flat. Even when it is sandwiched between other atomically flat crystals, it still slightly ripples. These out-of-plane corrugations, the deformation of the graphene layer into the third dimension, have profound
Our paper titled “A Double Quantum Dot Spin Valve” has appeared in Communications Physics. In this work, we reported a new approach for spin injection and spin detection in a semiconducting InAs NW device. We used two weakly-coupled semiconductor quantum dots (QDs)
Magnetic field independent sub-gap states in hybrid Rashba nanowires Most reports on the highly visible topic of Majorana Fermions in solid state systems are based on the observation of magnetic field independent transport resonances at zero bias, so-called zero-bias peaks.
Our paper entitled “Mobility Enhancement in Graphene by in situ Reduction of Random Strain Fluctuations” appeared in Phys. Rev. Lett. Bumps on a road slow down our pace, so do corrugations in graphene to travelling electrons. By flattening the corrugations
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
Simon Zihlmann successfully defended his PhD thesis “Spin and charge relaxation in graphene” on Friday 13th of April. We welcomed Prof. Dr. Bart J. van Wees (Univ. Groningen) and Porf. Dr. Christoph Stampfer (Univ. Aachen) as external PhD committee members.
One of the key properties of graphene for spintronics is its capability to transport spins over long distances unaltered. However, the need to manipulate the spins for information processing and storage is also of fundamental importance. The two dimensional heterostructure
