Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aelm201500073-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Electron transfer between graphene and an adsorbed molecule</bold> is systematically studied using a variety of electron acceptor/donor molecules. Doping efficiency is determined by the difference between the Fermi energy of graphene and the lowest unoccupied molecular orbital or highest unoccupied molecular orbital level of the molecule. The maximum carrier density accumulated by molecular adsorption is limited by the small density of states in graphene. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj22cdv7sc" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
