Optoelectronic properties of Ti3C2Tx thin films. (a) UV–vis spectra of films with various transmittance. (b) The relationship between transmittance (T) and sheet resistance (Rs). Also included are fitting curves and (T, Rs) from literature reports. (c) T–0.5 – 1 as a function of Rs to confirm the fitting value. (d) AFM image of a Ti3C2Tx film at T = 94% (MXene coverage 98%). (e) Height profiles of the different lines marked on (d). (f) Areas comprising different numbers of layers in (d) are shown with different colors. (g) Comparison of σDC/σop (FOMe) in various transparent conductive MXene films; detailed values are presented in Table S2. (i) Relationship between FOMe and MXene flake sizes.
