碳纳米电子学:将管解压缩成石墨烯带

Carbon nanoelectronics: unzipping tubes into graphene ribbons

H. Santos, L. Chico, L. Brey

摘要:

我们报道了由部分解链的碳纳米管制成的新型碳纳米结构的输运性质,该碳纳米结构可以被视为管和纳米管的无缝连接。我们发现,石墨烯纳米带在一定的能量范围内作为一个完美的谷过滤器的碳纳米管,具有最大可能的电导。我们的研究结果表明,部分解压缩的碳纳米管是一个磁阻器件,具有非常大的磁阻值。我们探讨了几种结构相结合的纳米管和石墨烯纳米带的性能,证明它们表现为最佳的接触,为彼此的混合石墨烯/纳米管器件的设计开辟了一条新的途径。

英文摘要:

We report on the transport properties of novel carbon nanostructures made of partially unzipped carbon nanotubes, which can be regarded as a seamless junction of a tube and a nanoribbon. We find that graphene nanoribbons act at certain energy ranges as a perfect valley filters for carbon nanotubes, with the maximum possible conductance. Our results show that a partially unzipped carbon nanotube is a magnetoresistive device, with a very large value of the magnetoresistance. We explore the properties of several structures combining nanotubes and graphene nanoribbons, demonstrating that they behave as optimal contacts for each other, and opening a new route for the design of mixed graphene/nanotube devices.
