This module will explain and discuss the great potential of MXenes for electronic applications. Owing to their extremely versatile chemical and structural composition, as well as surface chemistry, MXenes are one-of-a-kind materials for (opto)electronics, showing tunable and unique characteristics that might boost future technological progress. Here, participants will learn about the electronic properties of MXenes, their use in diverse electrical devices (e.g., transistors, photodetectors, memories, sensors), and singular interaction with the whole electromagnetic spectrum (from radio waves to X-rays). Much has been done, but the best is yet to come!
