In this work, we describe a new way to measure spin dependent charge capture events at MOSFET interfaces called near-zero-field spin dependent charge pumping (NZF SDCP) which yields similar information as conventional electron paramagnetic resonance. We find that NO anneals have a significant effect on the spectra obtained from 4H-SiC MOSFETs. We also likely resolve hyperfine interactions which are important for defect identification. Finally, we fully integrate a NZF SDCP measurement system into a wafer prober for high throughput applications.

The phosphate complex of sulphite oxidase in the Mo(V) oxidation state was investigated by e.p.r. spectroscopy. Third-derivative spectra reveal a wealth of structural detail previously unobserved in this spectrum. Most notable is the presence of hyperfine coupling from two inequivalent I = 1/2 nuclei, which we tentatively attribute to two 31P nuclei. Unresolved hyperfine interactions from at least one exchangeable 1H nucleus are also present.
