Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201500767-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A hybrid sol–gel dielectric bilayer structure</bold> yields a maximum energy density of 40 J cm⁻³ with a high extraction efficiency. The silica sol–gel dielectric is coated by an alkylphosphonic acid monolayer, as a charge‐blocking layer. The dense monolayer suppresses charge injection and electrical conduction, leading to high energy extraction efficiency, which exhibits nearly linear dielectric behavior suitable for high energy density applications. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgkfmpxnw7" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
