    摘要: Inverter logic devices include a gate oxide on a back substrate, a first graphene layer and a second graphene layer separated from each other on the gate oxide, a first electrode layer and a first semiconductor layer separated from each other on the first graphene layer, a second electrode layer and a second semiconductor layer separated from each other on the second graphene layer, and an output electrode on the first and second semiconductor layers and configured to output an output signal. The first semiconductor layer is doped with a different type of impurities selected from n-type impurities and p-type impurities than the second semiconductor layer.
