Stacking of MoS2 monolayers by sequential electrochemical thinning of bulk crystals

Abstract

Stacking of MoS2 is achieved via sequential electrochemical thinning (eTH) of bulk flakes directly on Au electrodes, enabling controlled large-area vertical stacks (≈ 550 µm). The approach preserves the 2H phase, minimizes oxidation, and enhances photoluminescence (≈ 6x) through interlayer decoupling, establishing a robust platform for electrochemical energy applications.
