Cs2AgBiBr6, as a benchmark lead-free double perovskite, has emerged promising alternative to lead-based perovskites because of its high stability, non-toxicity, exceptional optoelectronic properties, and multifunctionality. To encourage further research on Cs2AgBiBr6 broad applications, in this review, fundamental properties including the structure-property relation, synthesis, origin absorptio...

All van der Waals Fe 3 GeTe 2 /Cr Ge Te 6 /graphite magnetic heterojunctions have been fabricated via mechanical exfoliation and stacking, their magnetotransport properties are studied in detail. At low bias voltages, large negative junction magnetoresistances observed attributed to spin-conserving tunneling transport across an insulating Cr layer. With increasing bias, a crossover Fowler–Nordh...

A hexagonal analogue, Li6SiO4Cl2, of the cubic lithium argyrodite family solid electrolytes is isolated by a computation–experiment approach. We show that structure equivalent to antiperovskite electrolyte through anion site and vacancy ordering within stacking two close-packed layers. Construction models assemble these layers with combination motifs, both well known in large perovskite structu...

Antiphase boundaries (APB) in strontium ferromolybdate induce antiferromagnetically coupled spins of the Fe ions at boundary affecting both magnetic properties and electron transport across boundary. Herein, first, 3D presentation APB is presented. For first time, weighted antiferromagnetic (AF) modulus, bulk ferrimagnetic exchange stiffness constant, AF constant are estimated. This done by ana...

The optical properties of four new trinuclear chalcogenolato bridged metal complexes [Ag2Ti(SPh)6(PPh3)2], [Na(thf)3]2[Ti(SPh)6], [Cu2Ti(SePh)6(PPh3)2], and [Ag2Ti(SePh)6(PPh3)2] have been investigated by absorption photoluminescence spectroscopy as well time-dependent density functional theory (TDDFT) calculations compared to the results published recently for [Cu2Ti(SPh)6(PPh3)2]. All these c...
