We have successfully demonstrated a graphene-ZnO: N Schottky barristor. The barrier height between graphene and ZnO: N could be modulated by a buried gate electrode in the range of 0.5-0.73 eV, and an on-off ratio of up to 107 was achieved. By using a nitrogen-doped ZnO film as a Schottky contact material, the stability problem of previously reported graphene barristors could be greatly alleviated and a facile route to build a top-down processed graphene barristor was realized with a very low heat cycle. This device will be instrumental when implementing logic functions in systems requiring high-performance logic devices fabricated with a low temperature fabrication process such as back-end integrated logic devices or flexible devices on soft substrates.
