a r t i c l e i n f o Solution-based chalcogenide glass films, traditionally deposited by spin-coating, are attractive for their potential use in chip-based devices operating in the mid-infrared and for ease of nanostructure incorporation. To overcome limitations of spin-coating such as excessive material waste and difficulty for scale-up, this paper introduces electrospray as a film deposition...

In the proposed paper, we report chalcogenide As2Se3 glass Photonic Crystal Fiber (PCF) for dispersion compensating application and also demonstrate other dispersion properties (negative and zero dispersion) of As2Se3 glass PCF in different wavelength windows with hexagonal arrangement of air holes in the cladding using Improved Fully Vectorial Effective Index Method (IFVEIM).

Hierarchically-assembled binary cadmium chalcogenide (CdX, X = S, Se, Te) oligomers were engineered. CdTe precursor injections into a solution containing seeded nanocrystals provided longer oligomers possessing alternating and phase-separated CdX and CdTe constituents in the same wire, like an alternating copolymer.

Making contact to a quantum dot: Single quantum-dot electronic circuits are fabricated by wiring atomically precise metal chalcogenide clusters with conjugated molecular connectors. These wired clusters can couple electronically to nanoscale electrodes and be tuned to control the charge-transfer characteristics (see picture).

Free-standing "AMTIR-1" (Ge33As12Se55) chalcogenide glass films have been patterned using a focused ion beam (FIB) to create two-dimensional photonic crystal membranes. The triangular lattices were selected for a photonic bandgap relevant to fiber telecommunications. Optical measurements of transmission spectra as a function of incident angle showed clear signs of Fano resonances, indicating th...

The metal mesostructured Pt/Sn/Se chalcogenides with cubic MCM-48 type pore symmetry are found to be surprisingly stable in concentrated oxidizing acids. Their metal chalcogenide framework exhibits high flexibility during reversible proton exchange as it expands and contracts in an apparent breathing-like action.

A theoretical investigation into the chalcogenide Cu 2 SiSe 3 , revealing its potential as a defect-tolerant photovoltaic absorber.

A kind of molecular metal chalcogenide, (N(2)H(4))(3)(N(2)H(5))(4)Sn(2)Se(6) complex, was synthesized in the hydrazine solution and employed as the precursors for SnSe(2) deposition on TiO(2) nanocrystalline porous films. A power conversion efficiency of 0.12% under AM 1.5, 1 sun was obtained for the SnSe(2) sensitized TiO(2) solar cells.

A simple method to obtain homogeneous sub-monolayer coverage of metal oxide and chalcogenide nanocrystals onto porous oxide supports is described. Quantitative nanoparticle coverage was probed using photonic macroporous oxide supports. Composites of nanocrystals of TiO₂, Fe₃O₄ or CdS dispersed onto macroporous SiO₂ or ZrO₂ all show a predictable linear shift in the photonic stop band position.

We demonstrate highly efficient evanescent coupling between a highly nonlinear chalcogenide glass two dimensional photonic crystal waveguide and a silica fiber nanowire. We achieve 98% insertion efficiency to the fundamental photonic crystal waveguide mode with a 3dB coupling bandwidth of 12nm, in good agreement with theory. This scheme provides a promising platform to realize low power nanocav...
