Phase transition at 350 K in the Ti${}_3$C${}_2$T${}_x$ MXene: possible sliding (moiré) ferroelectricity

Francesco Cordero, Hanna Pazniak, Thierry Ouisse +4

A phase transition is found in Ti${}_3$C${}_2$T${}_x$ MXene at 350 K, by measuring the complex Young's modulus of self-standing thick films. A step-like softening and increase of the mec…
