Due to graphene\u2019s low optical absorptivity, graphene photodetector research so far has focused on hybrid systems to increase photoabsorption. However, such hybrid systems require a complicated integration process, and lead to reduced carrier mobility due to the heterogeneous interfaces.<\/p>\n<p><!-- Link: <a href=\"http:\/\/engineeringatil.scienceblog.com\/2016\/04\/06\/crumpling-approach-enhances-photodetectors-light-responsivity\/\">http:\/\/engineeringatil.scienceblog.com\/2016\/04\/06\/crumpling-...ponsivity\/<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>HUGE deal for wearables and biomed technologies.
