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

There are various ways to measure the magnetic field, for example, by the force exerted on a ferromagnetic needle, by the voltage measured at the two ends of a wire wound into a coil or through the Hall effect that

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.

One-dimensional edge transport in few-layer WTe2 In 2016 the Nobel Prize in Physics was given to three theorists who introduced a new state of matter, topological matter. A subclass is defined by topological insulators (TIs), which are crystals that are

Physicists of the Budapest University of Technology and Economics (BME) and the University of Basel discovered a surprising result on the extension of Yu-Shiba-Rusinov states. Their joint studies appeared in Nature Communications. Recently several promising novel qubit concepts have been

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

In this new publication, entitled: Highly symmetric and tunable tunnel couplings in InAs/InP nanowire heterostructure quantum dots Frederick and co-worker show that built-in quantum dots (QD) are very versatile for high resolution tunneling spectroscopy,   since the tunnel coupling strength G1 and G2  can be

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.
