Tailoring of a visible-light-absorbing biaxial ferroelectric towards broadband self-driven photodetection

Tailoring of a visible-light-absorbing biaxial ferroelectric towards broadband self-driven photodetection

2D lead-iodide ferroelectrics usually possess a wide bandgap along with the lacking of ferroelectric bulk photovoltaic effects due to the monolayered inorganic perovskite sheets. Here, the authors present a pathway to increase the thickness of inorganic sheets while retaining ferroelectricity.
