First observation on emergence of strong room-temperature ferroelectricity and multiferroicity in 2D-Ti₃C₂T _x free-standing MXene film.

ABSTRACT: Two-dimensional (2D) multiferroics are key candidate materials towards advancement of smart technology. Here, we employed a simple synthesis approach to address the long-awaited dream of developing ferroelectric and multiferroic 2D materials, especially in the new class of materials called MXenes. The etched Ti₃C₂T _x MXene was first synthesized after HF-treatment followed by a delamination process for successful synthesis of free-standing Ti₃C₂T _x film. The free-standing film was then exposed to air at room-temperature and heated at different temperatures to form a TiO₂ layer derived from the Ti₃C₂T _x MXene itself. The ferroelectric measurement showed a clear p
