Ultra-Wide Interlayered W_xMo_2xS_y Alloy Electrode Patterning through High-Precision Controllable Photonic-Synthesis.

ABSTRACT: Ultra-thin 2D materials have great potential as electrodes for micro-supercapacitors (MSCs) because of their facile ion transport channels. Here, a high-precision controllable photonic-synthesis strategy that provided 1 inch wafer-scale ultra-thin film arrays of alloyed W_xMo_2xS_y with sulfur vacancies and expanded interlayer (13.2 Å, twice of 2H MoS₂) is reported. This strategy regulates the nucleation and growth of transition metal dichalcogenides (TMDs) on the picosecond or even femtosecond scale, which induces Mo-W alloying, interlayer expansion, and sulfur loss. Therefore, the diffusion barrier of W_xMo_2xS_y is reduced, with charge transfer and ion diffusion enhancing. The as-prepared symmetric MSCs with the size
