The efficiency of these materials, however, has strong wavelength dependence, which limits their functionality to a narrow spectral range. Here, we report graphene-based electro-optical devices with unprecedented optical tunability covering the entire electromagnetic spectrum from the visible to microwave. We achieve this non-volatile and reversible tunability by electro-intercalation of lithium into graphene layers in an optically accessible device struct","authors_text":"Coskun Kocabas, Evgeniya Kovalska, Gokhan Bakan, Kostya Novoselov, Lewis W.
