Observation of Wigner crystal of electrons in a monolayer semiconductor
T. Smoleński, P. E. Dolgirev, C. Kuhlenkamp +9
When the Coulomb repulsion between electrons dominates over their kinetic energy, electrons in two dimensional systems were predicted to spontaneously break continuous translation…
Measuring local moiré lattice heterogeneity of twisted bilayer graphene
Tjerk Benschop, Tobias A. de Jong, Petr Stepanov +5
We introduce a new method to continuously map inhomogeneities of a moiré lattice and apply it to large-area topographic images we measure on open-device twisted bilayer graphene (T…
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…
Intrinsic Spin Photogalvanic Effect in Nonmagnetic Insulator
Ruixiang Fei, Xiaobo Lu, Li Yang
We show that with the help of spin-orbit coupling, nonlinear light-matter interactions can efficiently couple with spin and valley degrees of freedom. This revealed spin photogalva…
Terahertz photogalvanics in twisted bilayer graphene close to the second magic angle
M. Otteneder, S. Hubmann, X. Lu +6
We report on the observation of photogalvanic effects in twisted bilayer graphene (tBLG) with a twist angle of 0.6°. We show that excitation of tBLG bulk causes a photocurrent, who…
Artificial Multiferroics and Enhanced Magnetoelectric Effect in van der Waals Heterostructures
Yan Lu, Ruixiang Fei, Xiaobo Lu +3
Multiferroic materials with coupled ferroelectric and ferromagnetic properties are important for multifunctional devices due to their potential ability of controlling magnetism via…
