Research Statement

While some of the effects that are studied constitute classical spintronics questions, most of this work is focused on the exploration of spin-selection rule controlled electronic processes, a research domain that traditionally has not been part of spintronics but it encompasses a variety or research area including spin-quantum information research, defect spectroscopy, and radical pair chemistry. Spin-selection rules on electronic transitions preferably exist in materials with weak spin-orbit coupling, a natural focus of my work has therefore been on solids composed of carbon and silicon.

There are several motivators behind this research which include the search for physical processes which allow the invention and implementation of new spin-based information technologies, the search for electronic processes that can be utilized for quantum readout of spin-based quantum information technologies as well as the exploration the fundamental physical behavior of materials.

Among the results of this research over the past decade have been (i) the demonstration that spin-selection rules allow the sensitive detection of coherent spin motion of extremely small electron spin ensembles in semiconductor materials and insulators; (ii) that spin-selection rules can also be utilized for the coherent electrical readout of nuclear spins; (iii) that results (i) and (ii) can be applied for the implementation of a new, very sensitive magnetic resonance spectroscopy of paramagnetic states in condensed matter; (iv) that spin-selection rules can be used for optical and electrical dynamic nuclear polarization schemes (as needed for magnetic resonance imaging); (v) new insights into the nature of charge carrier transport and recombination in organic semiconductors such as pi-conjugated polymers or Fullerene derivatives and silicon based materials such as crystalline, microcrystalline, and amorphous silicon, silicon nitride and combinations thereof. (vi) that these results can be used for the invention of new spin-devices, most of all a new class of calibration free absolute thin-film magnetometers which are robust against environmental conditions such as temperature.
