Controlled alignment of supermoiré lattice in double-aligned graphene heterostructures
Junxiong Hu, Junyou Tan, Mohammed M. Al Ezzi +12
The supermoiré lattice, built by stacking two moiré patterns, provides a platform for creating flat mini-bands and studying electron correlations. An ultimate challenge in assembli…
Sliding induced multiple polarization states in two-dimensional ferroelectrics
Peng Meng, Yaze Wu, Renji Bian +13
When the atomic layers in a non-centrosymmetric van der Waals structure slide against each other, the interfacial charge transfer results in a reversal of the structures spontaneou…
The effect of temperature and excitation energy on Raman scattering in bulk HfS
Igor Antoniazzi, Natalia Zawadzka, Magdalena Grzeszczyk +6
Raman scattering (RS) in bulk hafnium disulfide (HfS) is investigated as a function of temperature (5 K 350 K) with polarization resolution and excitation of several laser…
Ultralow-noise terahertz detection by p-n junctions in gapped bilayer graphene
Elena Titova, Dmitry Mylnikov, Mikhail Kashchenko +6
Graphene shows a strong promise for detection of terahertz (THz) radiation due to its high carrier mobility, compatibility with on-chip waveguides and transistors, and small heat c…
Terahertz photoconductivity in bilayer graphene transistors: evidence for tunneling at gate-induced junctions
Dmitry Mylnikov, Elena I. Titova, Mikhail A. Kashchenko +6
Photoconductivity of novel materials is the key property of interest for design of photodetectors, optical modulators, and switches. Despite the photoconductivity of most novel 2d…
Giant gate-tunable renormalization of spin-correlated flat-band states and bandgap in a 2D magnetic insulator
Pin Lyu, Joachim Sødequist, Xiaoyu Sheng +8
Emergent quantum phenomena in two-dimensional van der Waal (vdW) magnets are largely governed by the interplay between the exchange and Coulomb interactions. The ability to tune th…
Unveiling the complex structure-property correlation of defects in 2D materials based on high throughput datasets
Pengru Huang, Ruslan luckin, Maxim Faleev +7
Modification of physical properties of materials and design of materials with on-demand characteristics is at the heart of modern technology. Rare application relies on pure materi…
Non-local correlation effects due to virtual spin-flip processes in itinerant electron ferromagnets
S. Paischer, G. Vignale, M. I. Katsnelson +2
We present an ab initio method for eletcronic structure calculations, which accounts for the interaction of electrons and magnons in ferromagnets. While it is based on a many body…
Mixing of surface and bulk electronic states at a graphite-hexagonal boron nitride interface

Excitons in thin layers of semiconducting transition metal dichalcogenides are highly subject to the strongly modified Coulomb electron-hole interaction in these materials. Therefo…
Non-conservation of the valley density and its implications for the observation of the valley Hall effect
Alexander Kazantsev, Amelia Mills, Eoin O'Neill +3
We show that the conservation of the valley density in multivalley insulators is broken in an unexpected way by the electric field that drives the valley Hall effect. This implies…
