The surface of MXene is heavily terminated by a mixture of -O, -F, and -OH functional groups as a result of MAX phase exfoliation via chemical etching. The 2D multilayers are cleaned by varying heat treatments and doped with other atoms of interest. The effects on thermal and electrical properties have been thoroughly investigated. The strong correlation of the electrical and thermal conductivity, and the measured Fano resonance contribution in the Raman spectra suggests that heat treatment reduces the number of electron-scattering defects rather than improving the interface boundaries. We provide an extensive experimental study of MXene films prepared under variable conditions and decorated with atoms of interest.
