Transport investigation of single nanowires

通过化学方法以棒或柱的形式生长的半导体纳米线的性质可以在宽范围内调节。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特性。将改进现有的操纵和接触这种导线的方法，并将进行运输实验。均匀纳米线、异质掺杂纳米线和纳米线异质结构的电子性质将被研究。详细的磁迁移实验延伸到高频率将允许在这些系统中的运输过程的理解。

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.
