Switching Graphitic Polytypes in Elastically Coupled Islands
Nirmal Roy, Simon Salleh Atri, Yoav Sharaby +5
Van der Waals polytypes are commensurate configurations of two-dimensional layers with discrete crystalline symmetries and distinct stacking-dependent properties. In graphitic poly…
Switchable Crystalline Islands in Super Lubricant Arrays
Youngki Yeo, Yoav Sharaby, Nirmal Roy +4
Expanding the performance of field effect devices is a key challenge of the ever-growing chip industry at the core of current technologies. A highly desired nonvolatile response in…
Polarization Saturation in Multi-layered Interfacial Ferroelectrics
Wei Cao, Swarup Deb, Maayan Vizner Stern +5
Van der Waals (vdW) polytypes of broken inversion and mirror symmetries were recently shown to exhibit switchable electric polarization even at the ultimate two-layer thin limit. T…
Shaping Exciton Polarization Dynamics in 2D Semiconductors by Tailored Ultrafast Pulses
Omri Meron, Uri Arieli, Eyal Bahar +3
The ultrafast formation of strongly bound excitons in two-dimensional semiconductors provide a rich platform for studying fundamental physics as well as developing novel optoelectr…
Spontaneous Electric Polarization in Graphene Polytypes
Simon Salleh Atri, Wei Cao, Bar Alon +8
A crystalline solid is a periodic sequence of identical cells, each containing one or more atoms. If the constituting unit cell is not centrosymmetric, charge may distribute uneven…
Superballistic flow of viscous electron fluid through graphene constrictions
R. Krishna Kumar, D. A. Bandurin, F. M. D. Pellegrino +13
Electron-electron (e-e) collisions can impact transport in a variety of surprising and sometimes counterintuitive ways. Despite strong interest, experiments on the subject proved c…
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…
Nanoscale thermal imaging of dissipation in quantum systems
Dorri Halbertal, Jo Cuppens, Moshe Ben Shalom +12
Energy dissipation is a fundamental process governing the dynamics of physical, chemical, and biological systems. It is also one of the main characteristics distinguishing quantum…
Negative local resistance caused by viscous electron backflow in graphene
D. A. Bandurin, I. Torre, R. Krishna Kumar +10
Graphene hosts a unique electron system in which electron-phonon scattering is extremely weak but electron-electron collisions are sufficiently frequent to provide local equilibriu…
Quantum oscillations of the critical current and high-field superconducting proximity in ballistic graphene
M. Ben Shalom, M. J. Zhu, V. I. Fal'ko +8
Graphene-based Josephson junctions provide a novel platform for studying the proximity effect due to graphene's unique electronic spectrum and the possibility to tune junction prop…
Quality heterostructures from two dimensional crystals unstable in air by their assembly in inert atmosphere
Y. Cao, A. Mishchenko, G. L. Yu +16
Many layered materials can be cleaved down to individual atomic planes, similar to graphene, but only a small minority of them are stable under ambient conditions. The rest reacts…
Nature of weak magnetism in SrTiO3/LaAlO3 multilayers
Z. Salman, O. Ofer, M. Radovic +12
We report the observation of weak magnetism in superlattices of LaAlO3/SrTiO3 using beta-detected nuclear magnetic resonance. The spin lattice relaxation rate of 8 Li in superlatti…
Anomalous magneto-transport at the superconducting interface between LaAlO3 and SrTiO3
M. Sachs, D. Rakhmilevitch, M. Ben Shalom +3
The magnetoresistance as a function of temperature and field for atomically flat interfaces between 8 unit cells of LaAlO3 and SrTiO3 is reported. Anomalous anisotropic behavior of…
