We report on the electrical characterization of single MXene Ti(3)C(2)Tx flakes ( where T is a surface termination) and demonstrate the metallic nature of their conductivities. We also show that the carrier density can be modulated by an external gate voltage. The density of free carriers is estimated to be 8 +/- 3 X 10(21) cm(-3) while their mobility is estimated to be 0.7 +/- 0.2 cm(2)/Vs. Electrical measurements, in the presence of a magnetic field, show a small, but clearly discernable, quadratic increase in conductance at 2.5 K. (C) 2016 AIP Publishing LLC.
