Abstract:
그라펜에지를드라이에칭한후 에칭된부분에물 또는알코올과같이수산화이온을제공할수 있는용액을접촉하여처리하면해당에지부분에작용기를도입할수 있다. 그라펜에지에작용기를도입함으로써그라펜의전기적성질을변화시킬수 있다. 전기적성질이변화된그라펜은센서나전계효과트랜지스터등 다양한소자에응용될수 있다.
Abstract:
탄소화 촉매 상에 형성된 그라펜 시트로부터 상기 탄소화 촉매를 제거하되, 상기 탄소화 촉매를 산화시킬 수 있는 산화제인 염 용액을 이용하여 상기 탄소화 촉매를 제거한다. 나아가, 이와 같이 탄소화 촉매가 제거된 그라펜 시트를 기판 또는 소자의 소정 위치에 전사한다. 이와 같은 방법에 의하여 그라펜 시트로부터 탄소화 촉매를 제거하면, 탄소화 촉매 제거 과정에서 발생할 수 있는 그라펜 시트의 손상을 방지 또는 억제할 수 있다. 그라펜 시트, 탄소화 촉매, 염 용액, 전사, 소수성 필름, 소수성 기판
Abstract:
Disclosed is a heterogeneous layered structure of a hexagonal boron nitride sheet (h-BN) and a graphene sheet, an electric device using the same, and a fabricating method thereof. The heterogeneous layered structure has a high quality interface state having few impurities between the h-BN sheet and the graphene sheet, by successively forming the graphene sheet with a vapor deposition method after a large-area h-BN sheet is grown on a metal substrate with a vapor deposition method. The heterogeneous layered structure of the h-BN and the graphene which has a high quality interface condition and a large area can be used for various electronic devices including a FET.
