Probing the Interlayer Exciton Physics in a MoS2/MoSe2/MoS2 van der Waals Heterostructure

Andras Kis, Dumitru Dumcenco, Yen-Cheng Kung, Alessandro Surrente

Stacking atomic monolayers of semiconducting transition metal dichalcogenides (TMDs) has emerged as an effective way to engineer their properties. In principle, the staggered band alignment of TMD heterostructures should result in the formation of interlay ...

Bending Rules in Graphene Kirigami

The three-dimensional shapes of graphene sheets produced by nanoscale cut-and-join kirigami are studied by combining large-scale atomistic simulations with continuum elastic modeling. Lattice segments are selectively removed from a graphene sheet, and the ...

Thermal Conductivity of Graphene and Graphite: Collective Excitations and Mean Free Paths

Nicola Marzari, Andrea Cepellotti, Lorenzo Paulatto, Giorgia Fugallo

We characterize the thermal conductivity of graphite, monolayer graphene, graphane, fluorographane, and bilayer graphene, solving exactly the Boltzmann transport equation for phonons, with phononphonon collision rates obtained from density functional pertu ...
