The electrical properties of graphite oxide (GO) can be tuned consecutively by treating samples with ammonia and hydrogen plasma. When altering ammonia plasma time from 10 to 4.5min, large area (greater than 100 × 100μm2), n-type, ambipolar and p-type semiconducting reduced graphite oxide (RGO) sheets could be obtained. The highest mobilities of the electron and hole are 5.41 and 2.10 cm2V-1 s-1 at low operational voltage (3 or -3V, respectively). When treating a GO film with hydrogen : argon (9 : 1) plasma, high conductivity RGO was obtained with conductivity around 630 S cm-1. It is anticipated that this study could pave the way towards carbonbased electronics. ©2013 The Author(s) Published by the Royal Society.
