Figure 4. (A) Band structures of semiconducting MXene systems (Fermi energy is located at zero). Reproduced from Ref.^[30] with permission from WILEY-VCH. (B) Stability of colloidal d-Ti₃C₂T_x in different environments. The dotted lines are the fitting results according to the empirical equation A = A_unre + A_ree^-t/τ. Reproduced from Ref.^[39] with permission from the American Chemical Society. (C) Strain-stress curves obtained by stretching Ti_n+1C_n materials. The dashed lines are extrapolated from the initial linear regions of strain-stress curves. Reproduced from Ref.^[44] with permission from IOP Publishing.
