The Interacting Energy Bands of Magic Angle Twisted Bilayer Graphene Revealed by the Quantum Twisting Microscope
J. Xiao, A. Inbar, J. Birkbeck +6
Electron interactions in quantum materials fundamentally shape their energy bands and, with them, the material's most intriguing quantum phases. Magic angle twisted bilayer graphen…
Imaging the Sub-Moiré Potential Landscape using an Atomic Single Electron Transistor
Dahlia R. Klein, Uri Zondiner, Amit Keren +10
Electrons in solids owe their properties to the periodic potential landscapes they experience. The advent of moiré lattices has revolutionized our ability to engineer such landscap…
Measuring Phonon Dispersion and Electron-Phason Coupling in Twisted Bilayer Graphene with a Cryogenic Quantum Twisting Microscope
John Birkbeck, Jiewen Xiao, Alon Inbar +7
The coupling between electrons and phonons is one of the fundamental interactions in solids, underpinning a wide range of phenomena such as resistivity, heat conductivity, and supe…
The Quantum Twisting Microscope
Alon Inbar, John Birkbeck, Jiewen Xiao +7
The invention of scanning probe microscopy has revolutionized the way electronic phenomena are visualized. While present-day probes can access a variety of electronic properties at…
Imaging Hydrodynamic Electrons Flowing Without Landauer-Sharvin Resistance
Chandan Kumar, John Birkbeck, Joseph A. Sulpizio +8
Electrical resistance usually originates from lattice imperfections. However, even a perfect lattice has a fundamental resistance limit, given by the Landauer conductance caused by…
Spread and erase -- How electron hydrodynamics can eliminate the Landauer-Sharvin resistance
Ady Stern, Thomas Scaffidi, Oren Reuven +3
It has long been realized that even a perfectly clean electronic system harbors a Landauer-Sharvin resistance, inversely proportional to the number of its conduction channels. This…
Composite super-moiré lattices in double aligned graphene heterostructures
Zihao Wang, Yi Bo Wang, J. Yin +23
When two-dimensional atomic crystals are brought into close proximity to form a van der Waals heterostructure, neighbouring crystals can start influencing each others electronic pr…
Imaging work and dissipation in the quantum Hall state in graphene
Arthur Marguerite, John Birkbeck, Amit Aharon-Steinberg +7
Topology is a powerful recent concept asserting that quantum states could be globally protected against local perturbations. Dissipationless topologically protected states are thus…
Visualizing Poiseuille flow of hydrodynamic electrons
Joseph A. Sulpizio, Lior Ella, Asaf Rozen +12
Hydrodynamics is a general description for the flow of a fluid, and is expected to hold even for fundamental particles such as electrons when inter-particle interactions dominate.…
Micromagnetometry of two-dimensional ferromagnets
M. Kim, P. Kumaravadivel, J. Birkbeck +14
The study of atomically thin ferromagnetic crystals has led to the discovery of unusual magnetic behaviour and provided insight into the magnetic properties of bulk materials. Howe…
Simultaneous imaging of voltage and current density of flowing electrons in two dimensions
Lior Ella, Assaf Rozen, John Birkbeck +8
Electron transport in nanoscale devices can often result in nontrivial spatial patterns of voltage and current that reflect a variety of physical phenomena, particularly in nonloca…
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…
Imaging resonant dissipation from individual atomic defects in graphene
Dorri Halbertal, Moshe Ben Shalom, Aviram Uri +8
Conversion of electric current into heat involves microscopic processes that operate on nanometer length-scales and release minute amounts of power. While central to our understand…
Edge currents shunt the insulating bulk in gapped graphene
M. J. Zhu, A. V. Kretinin, M. D. Thompson +13
An energy gap can be opened in the electronic spectrum of graphene by lifting its sublattice symmetry. In bilayers, it is possible to open gaps as large as 0.2 eV. However, these g…
