Transport investigation of single nanowires

用化学方法生长的棒状或柱状半导体纳米线的性质可以在很大范围内进行调整。因此，它们可以用于各种不同的应用，如连接线、二极管、晶体管等。在该项目中，将研究单个纳米线的电子性质。将改进现有的操纵和接触此类钢丝的方法，并进行运输试验。我们将研究均匀纳米线、异质掺杂纳米线和纳米线异质结的电学性质。扩展到高频的详细磁输运实验将使我们能够了解这些系统中的输运过程。

The properties of semiconducting nanowires which are grown by chemical methods in the form of rods or pillars can be adjusted in a wide range. Therefore, their use in a variety of different applications like connecting wires, diodes, transistors etc. is possible. Within the project the electronic properties of individual nanowires will be investigated. The existing methods for manipulating and contacting such wires will be improved and transport experiments will be carried out. The electronic properties of homogeneous nanowires, heterogeneously doped wires and nanowire heterostructures will be investigated. Detailed magnetotransport experiments extending up to high frequencies will allow for a understanding of the transport processes in these systems.
