Fast Growth of Centimeter-Scale Molybdenum Disulfide Single Crystal for Energy-Efficient Logic Circuits.

ABSTRACT: Two-dimensional transition metal dichalcogenides (TMDs) are promising candidates for next-generation electronics, but their future application is hindered by the inherently slow growth kinetics of conventional vapor deposition methods, particularly for the synthesis of large-area single-crystal films. Here, we demonstrate a source-confined chemical vapor deposition strategy that enables the fast synthesis of centimeter-scale MoS₂ single-crystal films within just 10 min. An optimized sandwich-structured Mo source was employed to ensure a concentration-balanced metal supply under sodium chloride catalysis, followed by sulfurization to form MoS₂. The films nucleate uniformly and directionally on the miscut C/A sapphire substrate positioned 2 cm upstream of the Mo source,
