Ti2CTx MXene‐based all‐optical modulator

Abstract MXenes, a new class of 2D transition metal carbides, nitrides, and carbonitrides, have attracted much attention due to their outstanding properties. Here, we report the broadband spatial self‐phase modulation of Ti2CT x MXene nanosheets dispersed in deionized water in the visible to near‐in...
