Fig. 3: Monolayer MXene capacitive response dependence on flake size.

a Electron micrograph of sample surface with flakes larger than 5 μm2 labelled. b Specific gravimetric capacitance on monolayer Ti3C2Tx compared to the total area Ti3C2Tx flake, obtained by normalizing capacitance by the mass of MXene in electrochemical contact with electrolyte. c Specific gravimetric capacitance obtained by normalizing by the total mass of the monolayer flake. Error bars represent the standard deviation from determination of b MXene mass contacted and c MXene flake mass.
