Ferroelectric perovskite-type films with robust in-plane polarization toward efficient room-temperature chemiresistive sensing.

ABSTRACT: Ferroelectric materials have become key components for versatile device applications, and their thin films are highly desirable for integrating the miniaturized devices. Despite substantial endeavors, it is still challenging to achieve effective chemiresistive sensing in the ferroelectric films. Here, for the first time, we have exploited ferroelectric thin films of 2D hybrid perovskite BA₂EA₂Pb₃I₁₀ (1), to fabricate the high-performance chemiresistor gas sensors. The spin-coated films of 1 exhibit high orientation and good crystallinity, thus preserving robust in-plane spontaneous polarization (P _s ∼2.0 μC/cm²) and low electric coercivity. Notably, such ferroelectric film-based sensors after elec
