Abstract. Hyperbolic media support high-k electromagnetic modes, enabling subdiffractional confinement, anomalous refraction, and enhanced light–matter int

Bismuth telluride (Bi2Te3) is a prototypical V–VI semiconductor of interest for both thermoelectric and topological applications; however, phase-selective synthesis and thermal stability across the bi...

Layered quasi-2D Cs2AgBiBr6 nanosheets, with large lateral dimensions of up to 1.4 µm, which are only a few nanometers thick, were synthesized as a result of systematic investigation of the roles of ...

Thiol-free hot injection approach yields quasi-2D klockmannite CuSe nanocrystals, specifically nanosheets and uniform triangular nanoplatelets. This study reconsiders the klockmannite from the point ....

We report a highly controlled colloidal synthesis of Bi nanosheets with tunable lateral sizes (0.6–4.1 µm), hexagonal shape, and a layered single-crystalline structure along the {00l} planes. The nan...

This research investigates plasmon-enhanced photodetection in quasi-2D-perovskite nanostripes incorporated with octadecanethiol-functionalized Ag nanostructure arrays. Spectral overlap between locali...

This study presents a novel strategy to enhance broadband photodetection in multilayer MoS2 by integrating CdSe/ZnS quantum dots with hexagonal nanoporous MoS2. Engineered sub-gap states facilitate e....

Current call for applications and information on the application process.

Metal halide perovskites are noted for their tunable optical properties. Colloidal synthesis allows the formation of differently shaped perovskite nanocrystals with varying optical and carrier transp...

Mechanisms by which excitons and charge carriers can funnel and recombine in 2D multi-layered MAPbBr3 Ruddlesden-Popper perovskite nanosheets are missing. This femtosecond transient absorption spectr...
