High-order minibands and interband Landau level reconstruction in graphene moire superlattice
Xiaobo Lu, Jian Tang, John R. Wallbank +13
The propagation of Dirac fermions in graphene through a long-period periodic potential would result in a band folding together with the emergence of a series of cloned Dirac points…
Imputation of missing sub-hourly precipitation data in a large sensor network: a machine learning approach
Benedict Delahaye Chivers, John Wallbank, Steven J. Cole +4
Precipitation data collected at sub-hourly resolution represents specific challenges for missing data recovery by being largely stochastic in nature and highly unbalanced in the du…
Tunnel spectroscopy of localised electronic states in hexagonal boron nitride
M. T. Greenaway, E. E. Vdovin, D. Ghazaryan +17
Hexagonal boron nitride (hBN) is a large band gap layered crystal, frequently incorporated in van der Waals (vdW) heterostructures as an insulating or tunnel barrier. Localised sta…
Excess resistivity in graphene superlattices caused by umklapp electron-electron scattering
J. R. Wallbank, R. Krishna Kumar, M. Holwill +11
Umklapp processes play a fundamental role as the only intrinsic mechanism that allows electrons to transfer momentum to the crystal lattice and, therefore, provide a finite electri…
Signatures of van Hove singularities probed by the supercurrent in a graphene - hBN superlattice
D. I. Indolese, R. Delagrange, P. Makk +4
The moiré superlattice induced in graphene by the hexagonal boron nitride substrate modifies strongly the bandstructure of graphene, which manifests itself by the appearance of new…
Transport through a network of topological states in twisted bilayer graphene
Peter Rickhaus, John Wallbank, Sergey Slizovskiy +10
We explore a network of electronic quantum valley Hall (QVH) states in the moiré crystal of minimally twisted bilayer graphene. In our transport measurements we observe Fabry-Pérot…
