Tunable hybrid perovskites with a narrow bandgap and multistage phase transition properties: 2,2-difluoroethylamine·antimony hexabromide

Abstract

Zero-dimensional perovskites have received extensive attention in recent years due to their unique structures, such as large exciton binding energy, strong quantum confinement effect, and good stability. Precisely construct target...

Effect of Pd(ii) uptake on high-temperature phase transitions in a hybrid organic–inorganic perovskite semiconductor

“…Differential scanning calorimetry (DSC) is a valid measurement to verify the properties of phase transitions. 53 We first performed DSC measurements on compounds 1 and 1-Pd in the range from 173 K to 440 K to detect the occurrence of phase transitions of the compounds under thermal stimulation. As depicted in Fig.…”

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

“…As a kind of high-tech material, crystal phase-transition materials have always been a subject of great interest. According to previous research, [18][19][20][21][22][23][24][25][26][27][28] one of the most feasible ways to design materials with dielectric response characteristics is by constructing materials that undergo temperature-induced phase transition.…”
