摘要: According to example embodiments, a graphene switching devices has a tunable barrier. The graphene switching device may include a gate substrate, a gate dielectric on the gate substrate, a graphene layer on the gate dielectric, a semiconductor layer and a first electrode sequentially stacked on a first region of the graphene layer, and a second electrode on a second region of the graphene layer. The semiconductor layer may be doped with one of an n-type impurity and a p-type impurity. The semiconductor layer may face the gate substrate with the graphene layer being between the semiconductor layer and the gate substrate. The second region of the graphene layer may be separated from the first region on the graphene layer.

摘要: A graphene electronic device and a method of fabricating the graphene electronic device are provided. The graphene electronic device may include a graphene channel layer formed on a hydrophobic polymer layer, and a passivation layer formed on the graphene channel layer. The hydrophobic polymer layer may prevent or reduce adsorption of impurities to transferred graphene, and a passivation layer may also prevent or reduce adsorption of impurities to a heat-treated graphene channel layer.
