    • PURPOSE: A graphene electric component is provided to improve mobility of a graphene channel layer by forming a plurality of nano-holes of a narrow interval on the graphene channel layer and to reduce depression of the graphene channel layer. CONSTITUTION: A gate oxide(120) is formed on a silicon substrate. A graphene channel layer(130) is formed on the gate oxide. A plurality of nano-holes(132) is arranged on the graphene channel layer in a lateral direction of the graphene channel layer. A source electrode(142) and a drain electrode(144) are formed on both ends of the graphene channel layer. A passivation layer covering the graphene channel layer is formed between the source electrode and the drain electrode. The diameter of each nano-hole is 1 to 20nm. The width of the graphene channel layer is 100nm to 5micrometers.
    • 目的:提供石墨烯电气部件以通过在石墨烯通道层上形成窄间隔的多个纳米孔并减少石墨烯通道层的压下来改善石墨烯通道层的迁移率。 构成:在硅衬底上形成栅极氧化物(120)。 在栅极氧化物上形成石墨烯通道层(130)。 在石墨烯通道层的横向方向上的多个纳米孔(132)被布置在石墨烯通道层上。 源极电极(142)和漏电极(144)形成在石墨烯通道层的两端。 在源电极和漏电极之间形成覆盖石墨烯沟道层的钝化层。 每个纳米孔的直径为1〜20nm。 石墨烯通道层的宽度为100nm至5微米。
