A self‐limiting growth process based on the interface‐controlled reaction of molten boron oxide (B 2 O 3 ) with ammonia (NH 3 ) is demonstrated for the facile and lost‐cost synthesis of ultrathin (20–30 nm) crystalline hexagonal boron nitride ( h ‐BN) films over large areas. The as‐grown h ‐BN films are of high quality, being densely continuous, uniform and smooth, and highly transparent over a broad wavelength range.
