説明

<jats:p>Controllable synthesis of large domain, high‐quality monolayer MoS<jats:sub>2</jats:sub> is the basic premise both for exploring some fundamental physical issues, and for engineering its applications in nanoelectronics, optoelectronics, etc. Herein, by introducing H<jats:sub>2</jats:sub> as carrier gas, the successful synthesis of large domain monolayer MoS<jats:sub>2</jats:sub> triangular flakes on Au foils, with the edge length approaching to 80 mm is reported. The growth process is proposed to be mediated by two competitive effects with H<jats:sub>2</jats:sub> acting as both a reduction promoter for efficient sulfurization of MoO<jats:sub>3</jats:sub> and an etching reagent of resulting MoS<jats:sub>2</jats:sub> flakes. By using low‐energy electron microscopy/diffraction, the crystal orientations and domain boundaries of MoS<jats:sub>2</jats:sub> flakes directly on Au foils for the first time are further identified. These on‐site and transfer‐free characterizations should shed light on the initial growth and the aggregation of MoS<jats:sub>2</jats:sub> on arbitrary substrates, further guiding the growth toward large domain flakes or monolayer films.</jats:p>
