The critical current of a superconductor can be different for opposite directions flow when both time-reversal and inversion symmetry are broken. Such non-reciprocal behaviour creates superconducting diode has recently been experimentally demonstrated by breaking these symmetries with an applied magnetic field or the construction tunnel junction. Here we report intrinsic effect that is present ...
We report on a theoretical study the rise of radiation-induced magnetoresistance oscillations in two-dimensional systems massive Dirac fermions. bilayer system monolayer graphene and hexagonal boron nitride (h-BN/graphene) trilayer encapsulated (h-BN/graphene/h-BN). extend radiation-driven electron orbit model that was previously devised to same Schr\"odinger electrons (GaAs/AlGaAS heterostruct...
Few-layer thick MoSe2 and WSe2 possess non-trivial spin textures with sizable spin splitting due to the inversion symmetry breaking embedded in the crystal structure and strong spin-orbit coupling. We report a spin-resolved photoemission study of MoSe2 and WSe2 thin film samples epitaxially grown on a bilayer graphene substrate. We only found spin polarization in the single- and trilayer sample...
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 react and decompose in air, which has severely hindered their investigation and potential applications. Here we introduce a remedial approach based on cleavage, transfer, alignment, and encapsulation of air-sensitive crystal...
Viscous electron hydrodynamics in high quality metals has been the subject of intense experimental activity recent years. This aided by development new imaging methods that allow for direct and noninvasive electronic flows metals. In this work, authors show diffusive, viscious, ballistic regimes anisotropic can be cleanly distinguished using a single image. They propose ABA-trilayer graphene as...
The properties of any material are fundamentally determined by its electronic band structure. Each band represents a series of allowed states inside a material, relating electron energy and momentum. The occupied bands, that is, the filled electron states below the Fermi level, can be routinely measured. However, it is remarkably difficult to characterize the empty part of the band structure ex...
The electronic structures of the nearly optimally doped single-layer, bilayer and trilayer Bi-based cuprates are investigated by angle-resolved photoemission spectroscopy. A lineshape analysis of data taken for different photon energies indicates that the interlayer coupling within the trilayer is not stronger than its counterpart in the bilayer system. This suggests that the higher Tc of the t...
We investigate the competition between acoustic phonon mediated superconductivity and long-range Coulomb interaction in moir\'eless graphene multilayers, specifically, Bernal bilayer graphene, rhombohedral trilayer ABCA-stacked tetralayer graphene. In these phonons can realize, through electron-phonon coupling, both spin-singlet spin-triplet pairings, intra-sublattice pairings ($s$-wave $f$-wav...
