Ferroelectric order in hybrid organic-inorganic perovskite nh4pbi3 with non-polar molecules and small tolerance factor

HIGHLIGHTS

• who: Jia-Bin Li from the (UNIVERSITY) have published the paper: Ferroelectric order in hybrid organic-inorganic perovskite NH4PbI3 with non-polar molecules and small tolerance factor, in the Journal: (JOURNAL)
• how: Although first-principles results indicated that its tetragonal phase favors a FE state21-24 there still be plenty of debates and controversy results from both experiments and theory25-33.

SUMMARY

Molecules in HOIP usually have hydrogen saturated structures and connects with inorganic frame through hydrogen_bonds. The effect of hydrogen_bonds, between molecules and the surrounding inorganic cage, is relatively weak . . .
