Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>By dimensionally constraining</bold> crystalline layers in a non‐epitaxial intergrowth, nanocrystal ensembles with well‐defined and precisely controlled size are prepared. Synchrotron X‐ray diffraction, electron microscopy, and density functional theory show that a size‐induced second‐order structural transition allows the crystal structure of a layered semiconductor (SnSe) to be continuously tuned by controlling the thickness of the individual layers.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t3kjszd" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
