Witryna11 cze 2024 · The impure phase has been falsely considered as the 1D δ-FAPbI 3. 16, 17, 18 Actually, the diffraction peak of the impure phase is at 11.47°, which has an obvious left shift in comparison with that of the pure δ-FAPbI 3 (11.74°). The left shift should result from small inclusions of the impurities, such as MFAI and DMFAI.

Witryna15 maj 2024 · No impure phase could be found in α-Cs 1-x FA x PbI 2 Br (0 ≤ x ≤ 0.4) films and hole-free surface could be get. Compared with α-CsPbI 2 Br, humidity stability and performance of α-Cs 1-x FA x PbI 2 Br were significantly enhanced by FA incorporation. The highest PCE can be 12.3% by 30% FA substitution. Witryna25 maj 2024 · For the solid phase test, we impose, using the previous experimental setup, temperatures of T G = 10 °C and T D = 15 °C (below melting temperature) on the left and right faces, respectively, until a thermal steady state is reached. The heat fluxes are initially constant. how many tourist goes at mount pinatubo

WitrynaA phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams … WitrynaThe BFO phase is stable under a narrow range of temperatures, and many other secondary phases of Fe and Bi can occur when oxygen partial pressure and temperature are not carefully controlled during the synthesis procedure [8]. Show abstract WitrynaWith the increase of temperature, impure phase were disappeared and the intensity of diffraction peaks strengthened. Pure BiFeO3 phase were obtained at 500 °C ~ 600 °C. When the heat treatment temperature increased above 650 °C, the impure phase appeared. SEM showed that the BFO thin film possessed a dense microstructure on … how many tourists does paris get each year
