Berry curvature-induced local spin polarisation in gated graphene/WTe2 heterostructures

Klaus Kern, Marko Burghard, Lukas Powalla

Experimental control of local spin-charge interconversion is of primary interest for spintronics. Van der Waals (vdW) heterostructures combining graphene with a strongly spin-orbit coupled two-dimensional (2D) material enable such functionality by design. ...

Reentrant magic-angle phenomena in twisted bilayer graphene in integer magnetic fluxes

Oleg Yazyev, Yifei Guan

In this Letter we address the reentrance of magic-angle phenomena (band flatness and quantum-geometric transport) in twisted bilayer graphene (TBG) subjected to strong magnetic fluxes +/-(1)0, +/- 200, +/- 3(p0 ... ((D0 = h/e is the flux quantum per moire ...

Single Skyrmion Generation via a Vertical Nanocontact in a 2D Magnet-Based Heterostructure

Klaus Kern, Marko Burghard, Lukas Powalla

Skyrmions have been well studied in chiral magnets and magnetic thin films due to their potential application in practical devices. Recently, monochiral skyrmions have been observed in twodimensional van der Waals magnets. Their atomically flat surfaces an ...

Light emission properties of mechanical exfoliation induced extended defects in hexagonal boron nitride flakes

Anna Fontcuberta i Morral, Nicolas Tappy

Recently, hexagonal boron nitride (hBN) has become an interesting platform for quantum optics due to its peculiar defect-related luminescence properties. Concomitantly, hBN was established as the ideal insulating support for realizing 2D materials devices, ...

Landau Levels as a Probe for Band Topology in Graphene Moire Superlattices

Oleg Yazyev, Quansheng Wu, Yifei Guan

We propose Landau levels as a probe for the topological character of electronic bands in two-dimensional moire superlattices. We consider two configurations of twisted double bilayer graphene (TDBG) that have very similar band structures, but show differen ...

Island formation of Er(trensal) single-ion magnets on graphene observed on the micrometer scale

Christian Wäckerlin, Jan Gui-Hyon Dreiser

We have studied the morphology of Er(trensal) single-ion molecular magnets adsorbed on graphene/Ru(0001) using X-ray photoemission electron microscopy (X-PEEM). By exploiting the elemental contrast at the erbium M-5 edge we observe the formation of molecul ...

Crystal Field Effect and Electric Field Screening in Multilayer Graphene with and without Twist

Oleg Yazyev, Quansheng Wu

We address the intrinsic polarization and screening of an external electric field in a broad range of ordered and twisted configurations of multilayer graphene, using an ab initio approach combining density functional theory and the Wannier function formal ...

Bottom-up synthesis of graphene films hosting atom-thick molecular-sieving apertures

Emad Oveisi, Kumar Varoon Agrawal, Kuang-Jung Hsu, Cédric Karel J Van Goethem, Kangning Zhao, Luis Francisco Villalobos Vazquez de la Parra, Mostapha Dakhchoune, Shiqi Huang, Shaoxian Li, Mina Moradi

Incorporation of a high density of molecular-sieving nanopores in the graphene lattice by the bottom-up synthesis is highly attractive for high-performance membranes. Herein, we achieve this by a controlled synthesis of nanocrystalline graphene where incom ...
