Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201401168-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A color‐selective, band‐engineered photodetector</bold> is demonstrated. The device uses two Schottky junctions to accumulate charge in an energy well, which results in photocurrent gain and a plasmonic aluminum grating for photocurrent enhancement and red–green–blue color selectivity. This work provides a more intelligent way to design imaging sensors by integrating amplifiers and color filters directly into pixels. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1f8bctr7" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
