Electron Transport through Nanostructures

Welcome to the website of Prof. Dr. Hilbert von Löhneysen's research unit "Electron Transport through Nanostructures" at the Institute of Nanotechnology at the Karlsruhe Institute of Nanotechnology. We focus on the experimental investigation of electronic transport properties of nanostructures, especially at low temperatures, where quantum effects play a dominant role.


EuS/aluminum structure
Spin transport in superconductors manipulated by spin-active scattering

We observe spin injection and long-range spin transport in nanoscale aluminum structures on top of the ferromagnetic insulator europium sulfide. Our results demonstrate that spin transport in superconductors can be manipulated by spin-active scattering.

Graphene microwave transistors on hexagonal boron nitride substrates driven by graphene nanoribbon backgates

Our new paper shows the possibilities of using graphene nanoribbons back-gates in microwave graphene field effect transistors on hexagonal boron nitride substrates.

Spin transport in superconductor hybrid structures
Long-range spin transport in nanoscale superconductors

In nanoscale superconductors with a Zeeman splitting, spin-polarized quasiparticles can be transported over suprisingly long distances. Read more in Hübler et al., Phys. Rev. Lett. 109, 207001 (2012)
