Decoupled Graphene Monolayers: Electrical Transport and Shot Noise

该项目的重点是由两个去耦单层组成的石墨烯纳米结构的制备和表征。平行和垂直于层流动的电流的磁输运测量允许调查的结构的电子特性。进行单层和双层的测量用于比较。研究了Aharanov-Bohm环几何中的相位相干输运。运输实验将辅之以散粒噪声测量。

The project focuses on the preparation and characterization of graphene nanostructures consisting of two decoupled monolayers. Magnetotransport measurements for currents flowing parallel and perpendicular to the layers allow to investigate the electronic properties of the structures. Measurements for single layers and bilayers are performed for comparison. Phase-coherent transport is investigated in Aharanov-Bohm ring geometries. The transport experiments will be complemented by shot noise measurements.
