Molecular Materials

The research activities of the Ruben-group at the Institute of Nanotechnology (INT) deal with the design of functional nano-systems by state-of-the-art organic/inorganic synthesis and supramolecular self-assembly techniques. At the INT, we are thematically organised in the interdisciplinary research topics of Functional Molecules, Molecular Electronics and Carbon-based Nanostructures.

Ir(ppy)3 as quantum transducer
Ir(ppy)3 as Quantum Transducer for Plasmon Generation

Controlling light at the nanoscale by electrical fields requires objects, in which electro-magnetic properties are responsive to gating fields. In two recent publications it was shown that molecules fulfil this requirement and act as such quantum transducers. This article was presented as research highlight in Nature Photonics.

Electrically driven nuclear spin resonance in single-molecule magnets A recent publication in Science shows how coherent single nuclear-spin manipulation using electric fields only can be achieved. This quantum-mechanical process is present in all nuclear spin systems and uses of the hyperfine Stark effect as a magnetic field transducer at the atomic level. Science June 2014

Nuclear Spin Read-out in Nature 2012
First Time Electronic Read-out of Nuclear Spin States For the first time nuclear spin states could be read out electronically by integrating single quantum magnets into circuits. Long nuclear spin lifetimes (tens of seconds) and exceptional relaxation characteristics at the single-atom scale open the way to a completely new device world, into which quantum logics may be implemented.

Real-space observation of spin-split molecular orbitals in adsorbed SMMs

In collaboration with the group of R. Wiesendanger we report the first direct real-space images of spin-split molecular orbitals at a TbPc2-Co(111) spinterface.
