Electron density difference of the (110) atomic plane among (a) Ti₃C₂Li₂, (b) Ti₃C₂F₂Li₂, (c) Ti₃C₂O₂Li₂, (d) Ti₃C₂Na₂, (e) Ti₃C₂F₂Na₂, (f) Ti₃C₂O₂Na₂ nanosheets for c-axis lattice constant of 25.04 Å, and among (g) Ti₃C₂Li₄, (h) Ti₃C₂F₂Li₄, (i) Ti₃C₂O₂Li₄, (j) Ti₃C₂Na₄, (k) Ti₃C₂F₂Na₄, (m) Ti₃C₂O₂Na₄ nanosheets for c-axis lattice constant of 35.04 Å. Blue color indicates the loss of electron density and red color indicates the enrichment of electron density compared with the sphere electron density in atoms. The color scale is in units of e.·Å.⁻³.
