摘要

用机械剥离法制备了数10 m长的石墨烯纳米带,并在0.3 K的低温下对其电输运性质进行了测量研究,看到了法布里-珀罗干涉现象. 实验结果表明,机械剥离法得到的石墨烯纳米带具有很高的质量,使得其中的电子在低温下能够形成一个很好的一维体系.

We have fabricated graphene nanoribbons (GNRs) of length up to tens of microns through mechanical cleavage, and performed electron transport measurements on devices made of the GNRs down to a low temperature of 0.3 K. Fabry-Perot interference was observed in the conductance of the devices as functions of both bias voltage and gate voltage. The result indicates that our mechanically cleaved GNRs are of high quality, in which the electrons form an ideal one-dimensional system at low temperatures.
