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 demonstrate, at room temperature, the strong coupling of the fundamental and non-uniform magnetostatic modes of an yttrium iron garnet ferrimagnetic sphere to the electromagnetic modes of a co-axial cavity.

We report the experimental observation of charge pumping in which a precessing ferromagnet pumps a charge current, demonstrating direct conversion of magnons into high-frequency currents via the relativistic spin–orbit interaction. The generated electric current, unlike spin currents generated by spin-pumping, can be directly detected without the need of any additional spin– charge conversion mechanism.

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.
