Implication

Observational analysis demonstrates enhanced ferroelectric properties in a 2D hybrid perovskite, highlighting its potential in piezoelectric sensing and optical applications.

Key Points

The 2D hybrid perovskite exhibits a large saturation polarization over 15 μC/cm2, significantly benefiting flexible device applications.
High Curie temperature of 401 K supports thermal stability, making it suitable for various functional devices.
Strong second harmonic generation intensity is 6.2 times that of KH2PO4, indicating remarkable optical properties.
This work offers a new pathway for creating high-performance 2D hybrid ferroelectrics via the synergy of lone pair and orientational ordering.
