Mid-infrared (IR) nonlinear optical (NLO) materials with high performance are vital to
expanding the laser wavelengths into the mid-IR region and have important technological …

Crystalline solids that exhibit inherently low lattice thermal conductivity (κlat) have attracted a
great deal of attention because they offer the only independent control for pursuing a high …

The physical properties of copper chalcogenides are mainly driven by the covalent nature of
Cu–S bonds. Although these phases have been studied extensively in the past decades, the …

The new compound NaCu4Se4 forms by the reaction of CuO and Cu in a molten sodium
polyselenide flux, with the existence of CuO being unexpectedly critical to its synthesis. It …

Novel chalcogenide materials exhibit remarkable thermal stability along with regulating
optoelectronic properties. The structural, optoelectronic, and transport properties of Na 4 XS …

Two new mixed metal ternary chalcogenides, NaScSe2 and NaScTe2, have been
synthesized by the high-temperature reaction of elements using the sealed tube method …

Context In the present work, the cubic phase of the chalcogenide materials, ie, A2MoSe4
(A= Li, K) is examined to explore the structural, optoelectronic, magnetic, mechanical …

Transition-metal tellurites have motivated growing research interest in both fundamental and
applied chemistry, and the corresponding single crystals could serve as rich and fascinating …

The two-dimensional material KCu3–x Se2 was synthesized using both a K2Se3 flux and
directly from the elements. It crystallizes in the CsAg3S2 structure (monoclinic space group …

Single-crystal and polycrystalline Ba4Cu8Se13 were synthesized; the average crystal
structure was solved by single-crystal X-ray diffraction, and the structural model was …
