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.

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
