This study demonstrates the first synthesis of MXene‐derived ferroelectric crystals. Specifically, high‐aspect‐ratio potassium niobate (KNbO3) ferroelectric crystals is successfully synthesized using 2D Nb2C, MXene, and potassium hydroxide (KOH) as the niobium and potassium source, respectively. Material analysis confirms that a KNbO3 orthorhombic phase with Amm2 symmetry is obtained. Additionally,...
In article number 1806860, Xixiang Zhang, Husam N. Alshareef, and co‐workers develop a process to derive KNbO3 ferroelectric crystals from two‐dimensional MXenes with excellent ferroelectric properties. The plate‐like ferroelectric crystals with c‐axis orientation inherit their morphology thanks to the two‐dimensional nature of the MXene precursor. KNbO3 is a very interesting material because it exhibits...
