Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201470113-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>On page 2737, Q. Gan, S. Jiang, and co‐workers develop a fundamental strategy to enhance the light‐matter interaction of ultra‐thin (i.e., 1.5–3 nm) Ge films based on a strong interference effect in planar nanocavities, and overcome the limitation between the optical absorption and film thickness of energy‐harvesting/conversion materials. This principle is quite general and can be applied to explore the spectrally tunable absorption enhancement of various ultra‐thin absorbing materials. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg5nnfnbmw" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
