Effect of Synthesis on Quality, Electronic Properties and Environmental Stability of Individual Monolayer Ti 3 C 2 MXene Flakes

2D transition metal carbide Ti 3 C 2 T x (T stands for surface termination), the most widely studied MXene, has shown outstanding electrochemical properties and promise for a number of bulk applications. However, electronic properties of individual MXene flakes, which are important for understanding the potential of these materials, remain largely unexplored. Herein, a modified synthetic method is reported for producing high‐quality monolayer Ti 3 C 2 T x flakes. Field‐effect transistors (FETs) based on monolayer Ti 3 C 2 T x flakes are fabricated and their electronic properties are measured. Individual Ti 3 C 2 T x flakes exhibit a high conductivity of 4600 ± 1100 S cm −1 and field‐effect electron mobility of…
