Two-Dimensional Metal–Chalcogenide Films in Tunable Optical Microcavities

Integration of quasi-two-dimensional (2D) films of metal-chalcogenides in optical microcavities permits new photonic applications of these materials. Here we present tunable microcavities with monolayer MoS2 or few monolayer GaSe films. We observe significant modification of spectral and temporal properties of photoluminescence (PL): PL is emitted in spectrally narrow and wavelength-tunable cav...

Two-dimensional transition metal dichalcogenide (TMD) nanosheets.

This special issue is about two-dimensional transitionmetal dichalcogenides (2DTMDs), a family of materials consisting of over 40 compounds with the generalized formula of MX2, where M is a transition metal typically from groups 4–7, and X is a chalcogen such as S, Se or Te. Bulk TMDs have been widely studied over several decades because it is possible to formulate compounds with disparate elec...

Strain effects in low-dimensional transition metal oxides

Transition metal oxides offer a wide spectrum of properties which provide the foundation for a broad range of potential applications. Many of these properties originate from intrinsic coupling between lattice deformation and nanoscale electronic and magnetic ordering. Lattice strain thus has a profound influence on the electrical, optical, and magnetic properties of these materials. Recent adva...

Intrinsic magnetism of grain boundaries in two-dimensional metal dichalcogenides.

Grain boundaries (GBs) are structural imperfections that typically degrade the performance of materials. Here we show that dislocations and GBs in two-dimensional (2D) metal dichalcogenides MX2 (M = Mo, W; X = S, Se) can actually improve the material by giving it a qualitatively new physical property: magnetism. The dislocations studied all display a substantial magnetic moment of ∼1 Bohr magne...

Intrinsic Two-Dimensional Organic Topological Insulators in Metal-Dicyanoanthracene Lattices.

We predict theoretical existence of intrinsic two-dimensional organic topological insulator (OTI) states in Cu-dicyanoanthracene (DCA) lattice, a system that has also been grown experimentally on Cu substrate, based on first-principle density functional theory calculations. The pz-orbital Kagome bands having a Dirac point lying exactly at the Fermi level are found in the freestanding Cu-DCA lat...
