Structure-imposed electronic topology in cove-edged graphene nanoribbons
Florian M. Arnold, Tsai-Jung Liu, Agnieszka Kuc +1
In cove-edged zigzag graphene nanoribbons (ZGNR-C), one terminal CH group per length unit is removed on each zigzag edge, forming a regular pattern of coves which controls their el…
Transport of hydrogen isotopes through interlayer spacing in van der Waals crystals
S. Hu, K. Gopinadhan, A. Rakowski +7
Atoms start behaving as waves rather than classical particles if confined in spaces commensurate with their de Broglie wavelength. At room temperature this length is only about one…
Defect healing and charge transfer mediated valley polarization in MoS/MoSe/MoS trilayer van der Waals heterostructures
Alessandro Surrente, Dumitru Dumcenco, Zhuo Yang +7
Monolayer transition metal dichalcogenides (TMDC) grown by chemical vapor deposition (CVD) are plagued by a significantly lower optical quality compared to exfoliated TMDC. In this…
Control of biaxial strain in single-layer Molybdenite using local thermal expansion of the substrate
G. Plechinger, A. Castellanos-Gomez, M. Buscema +6
Single-layer MoS2 is a direct-gap semiconductor whose electronic band structure strongly depends on the strain applied to its crystal lattice. While uniaxial strain can be easily a…
