Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201501354-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Grain boundaries</bold> in as‐grown polycrystalline MoS₂ monolayers are revealed by second‐harmonic‐generation microscopy. Through the anisotropic polarization pattern and phase interference at the grain boundary, grain edge termination and boundary types are identified. Statistical analysis on hundreds of grains shows that grain‐boundary formation is driven by kinetics and can be nicely described by the edge attachment growth model. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj1smmh2xc" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
