Reactive-ion-etched graphene nanoribbons on a hexagonal boron nitride substrate

摘要: We report on the fabrication and electrical characterization of both single layer graphene micron-sized devices nanoribbons a hexagonal boron nitride substrate. show that have significantly higher mobility lower disorder density compared to fabricated silicon dioxide substrate in agreement with previous findings. The transport characteristics reactive-ion-etched nitride, however, appear be very similar those ribbons perform detailed study order highlight similarities as well differences. Our findings suggest edges an important influence nanodevices.
