Abstract

<abstract abstract-type="graphical" xml:lang="en" id="smll201570113-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>On page 2392, W. Hu, L. Liao, and co‐workers report a large enhancement of the photoresponse in few‐layer MoS₂ phototransistors by coupling few‐layer MoS₂ with plasmonic nanostructures. Gold nanostructures, such as periodic nanoplates or randomly distributed nanoparticles, can excite localized surface plasmonic resonance waves under illumination, thus manipulating the direction of incident light propagation at a specific wavelength. In this manner, gold nanostructures can enhance the light‐absorption efficiency as well as the photoresponsivity of MoS₂ phototransistors. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjng669hr" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
