Organic light emitting diodes (OLEDs) based on thermally activated delayed fluorescence (TADF) can be highly efficient because of the conversion of non-radiative triplet to radiative singlet states by reverse intersystem crossing (RISC). Even highly

Control of the effective local hyperfine fields in a conjugated polymer, poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene] (MEHPPV), by isotopic engineering is reported. These fields, evident as a frequency-independent line broadening mechan

Certain species of living creatures are known to orientate themselves in the geomagnetic field. Given the small magnitude of approximately 48 {\mu}T, the underlying quantum mechanical phenomena are expected to exhibit coherence times approaching the

Spin transport in thin-film materials can be studied by ferromagnetic resonantly (FMR) driven spin pumping of a charge-free spin current which induces an electromotive force through the inverse spin Hall effect (ISHE). For quantitative ISHE experimen

Spin-dependent processes play a crucial role in organic electronic devices. Spin coherence can give rise to spin mixing due to a number of processes such as hyperfine coupling, and leads to a range of magnetic field effects. However, it is not straig

Separating the influence of hyperfine from spin-orbit interactions in spin-dependent carrier recombination and dissociation processes necessitates magnetic resonance spectroscopy over a wide range of frequencies. We have designed compact and versatil

Exploration of spin-currents in organic semiconductors (OSECs) induced by resonant microwave absorption in ferromagnetic substrates has been of great interest for potential spintronics applications. Due to the inherently weak spin-orbit coupling (SOC

In this thesis a connectionist model for affordance-guided selective attention for action is presented. The selective attention for action model (SAAM) is aimed at modelling the direct route from vision to action using Gibson's affordances to describ
