Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>M. Terrones and co‐workers design a photodetector consisting of a few‐layered WS2 film on quartz with Au/Ti contacts. <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">On page 5511</ext-link>, different laser wavelengths are applied perpendicularly to the film. The few‐layered films of WS2 are synthesized by chemical vapor deposition and the photodevices exhibit very fast responses (on the order of 5 ms). The excellent response of few‐layered WS2 to detect different photon wavelengths over a wide range of intensities makes it a strong candidate for constructing novel optoelectronic devices. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t6qq5ss" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
