Figure Lengend Snippet: (a) XRD patterns of as-deposited −60 nm nominal thickness - Ti 3 AlC 2 thin films (I), Ti 3 C 2 T x after etching in 50% HF for 2 h 40 min (II), and Ti 3 C 2 T x -IC after etching in 1 M NH 4 HF 2 for 11 h (III). XPS spectra of, (b) Ti 2p, (c) C 1s, and (d) Al 2p for Ti 3 AlC 2 , Ti 3 C 2 T x , and Ti 3 C 2 T x -IC thin films, respectively. The vertical lines in panels b and c indicate the positions of Ti (3/2p and 1/2p) and C (1s) binding energies in TiC, respectively. (e) High resolution XPS spectra for N 1s region for Ti 3 C 2 T x -IC, best fitted by symmetric Gaussian–Lorentzian curves resting on a Shirley background. The two components correspond to (NH 4 +1 ) and (NH 3 ).
