Ziel

The investigation of the transport properties of nanoscaled objects is a strongly expanding field of nowadays solid-state physics, it attracts increasing attention either in applied science due to the potential in future applications or in basics research due to exciting quantum effects on the nanoscale.
Semiconducting nanowires (NW) are single crystals with a typical diameter of 10-100nm and length of 5-10microm. Fabricating metallic leads to NWs, devices can be produced, where the electron density can be strongly varied by gates and the transport can be explored from the quasi-ballistic to the quantum dot regime. Due to their exceptional properties (e.g. band structure engineering, possibility to contact them with ferromagnetic (F), superconducting (S) leads, local gating), NW based devices open a new horizon in quantum transport.

In order to be competitive in the field of experimental quantum electronics, it is essential to own sample fabrication facilities, which has not been available in the host institute. The main aim of this proposal is to set up the environment of device fabrication, which will be based on a Jeol scanning electron microscope equipped with lithography unit.

The applicant will fabricate and investigate the low temperature transport properties of InAs NW based devices focusing mainly on spin injection from ferromagnetic leads and on F-S hybrid nanostructures. The fabrication facility will also support other ongoing quantum electronic projects.
