Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A self‐limiting growth process</bold> based on the interface‐controlled reaction of molten boron oxide (B₂O₃) with ammonia (NH₃) is demonstrated for the facile and lost‐cost synthesis of ultrathin (20–30 nm) crystalline hexagonal boron nitride (<italic>h</italic>‐BN) films over large areas. The as‐grown <italic>h</italic>‐BN films are of high quality, being densely continuous, uniform and smooth, and highly transparent over a broad wavelength range. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1xrnm29w" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
