Probing the optical near-field interaction of Mie nanoresonators with atomically thin semiconductors
Ana Estrada-Real, Ioannis Paradisanos, Peter R. Wiecha +10
Optical Mie resonators based on silicon nanostructures allow tuning of light-matter-interaction with advanced design concepts based on CMOS compatible nanofabrication. Optically ac…
Planar bridging an atomically precise surface trench with a single molecular wire on an Au(111) surface
Umamahesh Thupakula, Xavier Bouju, Jesús Castro-Esteban +3
In a bridge configuration, a single graphene nanoribbon (GNR) is positioned with a picometer precision over a trench in between two monoatomic steps on an Au(111) surface. This GNR…
Tuning the magnetic interactions in van der Waals FeGeTe heterostructures: A comparative study of \textit{ab initio} methods
Dongzhe Li, Soumyajyoti Haldar, Tim Drevelow +1
We investigate the impact of mechanical strain, stacking order, and external electric fields on the magnetic interactions of a two-dimensional (2D) van der Waals (vdW) heterostruct…
Surface Vacancy Generation by STM Tunneling Electrons in the Presence of Indigo Molecules on Cu(111)
Carlos Javier Villagómez, Fernando Buendía, Lauro Oliver Paz-Borbón +3
Herein, we invesgate the consequence of local voltage pulses on the adsorption state of single indigo molecules on the Cu(111) surface as well as on the atomic structure underneath…
Strain-Driven Zero-Field Near-10 nm Skyrmions in Two-Dimensional van der Waals Heterostructures
Dongzhe Li, Soumyajyoti Haldar, Stefan Heinze
Magnetic skyrmions localized chiral spin structures show great promise for spintronic applications. The recent discovery of two-dimensional (2D) magnetic materials opened n…
Proposal for all-electrical spin manipulation and detection for a single molecule on boron-substituted graphene
Fei Gao, Dongzhe Li, Cyrille Barreteau +1
All-electrical writing and reading of spin states attract considerable attention for their promising applications in energy-efficient spintronics devices. Here we show, based on ri…
