Nanospintronics

The field of spin electronics or "spintronics" aims to understand how one can make use of the spin degree of freedom of electrons in order to realize electronic devices and functionalities which cannot be realized by making use of the electron's charge degree of freedom alone.

Electron spins in silicon

We aim to control single electron spins in silicon where a long spin lifetime is expected due to the low spin-orbit coupling and also a low density of nuclear spins. In our research, the electrons are either confined in the atomic-like potential of a single dopant or in a quantum dot.

We observe the real-time breaking of single Cooper pairs by monitoring the radio-frequency impedance of a superconducting double quantum dot. In addition, we measure in real time the quasiparticle recombination into Cooper pairs. Analysis of the recombination rates shows that, in contrast to bulk films, a multistage recombination pathway is followed.

Current-induced torques in ultrathin Co/Pt bilayers were investigated. As the ferromagnet thickness was reduced from 3 to 1 nm, the sign of the sum of the field-like torque and Oersted torque reversed. This observation is consistent with the emergence of a Rashba spin orbit torque in ultra-thin bilayers.

A metallic double dot is measured with radio frequency reflectometry. Electron counting experiments are performed by monitoring the impedance, demonstrating operation of a single electron ammeter without the need for external charge detection.

Here, we report the observation of an antidamping spin–orbit torque that stems from the Berry curvature, in analogy to the origin of the intrinsic spin Hall effect. We expect the torque to be of comparable strength to the spin-Hall-effect-driven antidamping torque in ferromagnets interfaced with paramagnets with strong intrinsic spin Hall effect.
