Probing the graphene/substrate interaction by electron tunneling decay
Virginia Carnevali, Alessandro Sala, Pietro Biasin +4
The electronic properties of graphene can be modified by the local interaction with a selected metal substrate. To probe this effect, Scanning Tunneling Microscopy is widely employ…
Imaging at the mesoscale (LEEM, PEEM)
Alessandro Sala
*To be published in Springer Handbook of Surface Science (Springer Verlag) [Preprint]* The capability to display images containing chemical, magnetic and structural information and…
Bloch-point-mediated topological transformations of magnetic domain walls in cylindrical nanowires
Olivier Fruchart, A Wartelle, B Trapp +11
Cylindrical nanowires made of soft magnetic materials, in contrast to thin strips, may host domain walls of two distinct topologies. Unexpectedly, we evidence experimentally the dy…
Electronic properties of WS on epitaxial graphene on SiC(0001)
Stiven Forti, Antonio Rossi, Holger Büch +12
This work reports an electronic and micro-structural study of an appealing system for optoelectronics: tungsten disulphide WS on epitaxial graphene (EG) on SiC(0001). The WS$_2…
Magnetic skyrmions in confined geometries : effect of the magnetic field and the disorder
Roméo Juge, Soong-Geun Je, Dayane de Souza Chaves +13
We report on the effect of the lateral confinement and a perpendicular magnetic field on isolated room-temperature magnetic skyrmions in sputtered Pt/Co/MgO nanotracks and nanodots…
Tuning the Electronic Structure of Monolayer Graphene/MoS2 van der Waals Heterostructures via Interlayer Twist
Wencan Jin, Po-Chun Yeh, Nader Zaki +9
We directly measure the electronic structure of twisted graphene/MoS2 van der Waals heterostructures, in which both graphene and MoS2 are monolayers. We use cathode lens microscopy…
