报告内容：
Ferroelectricity in halide perovskites currently represents a crucial issue as it may have an important role for the enhancement of solar cells efficiency. Simulations of ferroelectric properties based on density functional theory are conceptually more demanding compared with “conventional inorganic ferroelectrics due to the presence of both organic and inorganic components in the same compound. Here we present a detailed study focused on the prototypical (CH3NH3)PbI3 perovskite and the lead-free ferroelectric perovskite iodide (FA)SnI3 containing the planar formamidinium cation.
