Hybrid organic–inorganic perovskites offer versatile platforms for tuning light emission through their chemical composition and structural dimensionality. However, achieving tunable broadband emission in single-phase lead iodide systems remains challenging. In this work, we present the synthesis, structural characterization, and optical properties of a two-dimensional hybrid perovskite,...

Compositional engineering through metal mixing is an important strategy for tailoring the structural and functional properties of hybrid metal halide perovskites.[1] While extensive research has focused on mixing organic cations at the A-site and halide anions at the X-site,[2] the effects of B-site mixing on phase stability and structural transitions remain less explored. In this work, we...

Hybrid organic-inorganic perovskites (HOIPs) have attracted considerable attention in recent years. These materials are characterized by the general formula ABX3 (where A is an organic cation, B is a metal cation, and X is a halide anion) and exhibit unique semiconducting properties. Driven by extensive research, these compounds have been successfully integrated as active layers in...

Ten new hybrid coordination compounds containing the octahedral tris(2,2′-bipyridine)ruthenium(II) cation and structurally diverse metal chloride anions were synthesized and characterized by single-crystal X-ray diffraction. The inorganic components exhibit remarkable structural diversity; the formation of discrete tetrahedral anions [CoCl4]2–,...

Heat and thermal radiation are large components of energy provided by direct sun radiation (where infrared constitutes a significant portion), terrestrial radiation, byproducts of industrial and agricultural activity, physical, chemical and biological processes in nature as well. However, a subsequent conversion of thermal energy into other useful forms such as electricity or mechanical work...

Quaternary chalcogenides based on Cu₂ZnSnS₄ (CZTS) are attracting attention as earth-abundant, low-cost semiconductor materials for thin-film photovoltaics (PV) and thermoelectric (TE) applications. Substituting Zn with transition metals such as Ni, Fe, and Co offers opportunities to modify cation distribution, defect structure and electronic properties.

Vanadium oxide (VOX) thin films of different phase composition and stoichiometry (1.5< x< 2.5) are widely used in nano- and micro-electronics, sensors, applied optics, and energy-saving technologies. There are about 20 phases of vanadium-oxygen system including main (VO, V2O3, V3O5, VO2, V2O5) and defective (VnO2n-1, VnO2n+1, etc) phases. Of particular interest are the VO2 phase, which have...

The nominal cut-off frequency of a semiconductor transistor does not necessarily mark the end of its potential for radio-frequency and terahertz applications. This talk explores the physics, development, and performance of antenna-coupled field-effect transistor detectors (TeraFETs) fabricated in CMOS technology, highlighting how nonlinear effects enable detection far beyond conventional...
