Control of quantum transport in atomic-scale graphene devices

我们试图将自上而下的纳米制造与有机合成相结合，通过化学修饰来控制石墨烯片的边缘。通过我们在核聚变研究基础上的制造和表征方面的进步，有可能使量子纳米器件小到接近分子尺度。在这项研究中，我们提出了一种选择性氧化方法，只功能化石墨烯片的边缘。我们的实验结果是石墨烯边缘结构控制的重要一步。我们将把化学改性应用到器件的制造过程中，作为未来的工作。

We try to develop new fabrication process that combines the top-down nanofabrication and organic synthesis to control the edge of graphene sheets by chemical modification. Through advances in fabrication and characterization building on our fusion research, it may become possible to make quantum nanoedevices so small that they approach the molecular scale. In this research, we present a selective oxidation method that functionalizes only the edges of graphene sheets. Our experimental results are important step toward the control of edge structures in graphene. We will apply the chemical modification to the device fabrication process as a future work.
