Ionic liquid engineering is also an effective approach to stabilize black α-FAPbI 3. DMF and DMSO are usually used in combination to retard perovskite crystallization, and the experi-ment was processed in an inert atmosphere with strict con-trol of both ...
we introduce the anharmonic coupling model to demonstrate that the polaron THz emission corresponds to a phonon mode with strong electron-phonon coupling between Dember current and ionic lattice. Before photoexcitation, the ionic lattice and organic cation collectively vibrate near the equilibrium position...
Ab initio molecular dynamics simulations are performed to unravel the complex dynamic behaviors of BF4-based ionic liquids (ILs) at the SnO2/FAPbI3 interface. Specifically, the BMIM+BF4 IL not only eliminates the density of states induced by oxygen vacancies in SnO2, but also significantly ...
a Based on an ionic radius of 0.93 Å for Sb3+ [50]. LT : low temperature. In first intention, we treat the Stokes shift as ΔS=2Sℏω(A1g)Δr2 with ћω(A1g) the energy of the symmetric A1g breathing mode of the ideal quasi molecular (SbX6)3- octahedron (X = Cl, Br...
Similarly, interface engineering was applied to either passivate interface defects or establish proper energy barriers at the interface5,22,23. Finally, judicious selec- tion of precursors and anionic species was found to be efficient in alleviating hysteresis problems due to ionic species5,6,9. 1...
[14]. The defect structure, vacancy ordering, and oxygen ion transport in the Bi3YO6δ-phase were studied using ab initio molecular dynamic, as well as total neutron scattering analysis [15,16,17]. Ionic transport in a material and its defect structure are commonly tested in Bi3NbO7-Bi3...
