Dielectric and optical properties of a new organic–inorganic hybrid phase transition material

Abstract

Crystal phase transformation is often accompanied with the change of corresponding physical properties. For instance, dielectric properties may undergo abrupt changes near phase transition temperatures. For organic-inorganic hybrid materials, designing...

Novel One-Dimensional Organic–Inorganic Hybrid Halide Perovskite Material with Coexistence of High Phase Transition Temperature and Corresponding Dielectric Response

“…The temperature ranged from 394 to 460 K. The real dielectric part of the constant was tested through TH2828S. The testing methodology aligns with that outlined in the preceding article, incorporating frequencies of 500 Hz, 1 kHz, 5 kHz, 10 kHz, 100 kHz, and 1 MHz throughout both the heating and cooling processes …”

“…The testing methodology aligns with that outlined in the preceding article, incorporating frequencies of 500 Hz, 1 kHz, 5 kHz, 10 kHz, 100 kHz, and 1 MHz throughout both the heating and cooling processes. 16 Single-Crystal Structure Determination. In order to understand the reason for the phase transition from the microstructure, a single-crystal structure test was done through a Bruker D8 Venture diffractometer, which operated in graphite-monochromator Mo−Kα radiation (λ = 0.71073 Å).…”

High temperature switchable dielectric properties in molecular crystal material 1,4,7-triazacyclononane trihydrochloride

“…1–6 Dielectric switching materials are special structural phase transition materials, that is, the structure of the phase transition material changes under the stimulation of temperature increase/decrease, and the symmetry of the crystal is reorganized/broken, causing dielectric changes in related physical and chemical properties such as constants. 7–10 Different types of materials have their own characteristics and advantages and disadvantages. For example, inorganic materials have better structural stability and performance, organic materials are lightweight and have diverse structures, and organic–inorganic hybrid materials have the characteristics of both organic and inorganic materials.…”
