Ravi Acharya: Focused Ion Beam Isotopic Engineering and Electrical Detection of Group-V Donors for Silicon-Based..., Gebunden

Klappentext

This book reports experimental work delivering a route to the successful isotopic enrichment of 28-silicon for providing a solid-state spin vacuum platform suitable for quantum computing. The levels of isotopic purification achieved reduce the nuclear spin carrying 29-silicon isotope to below 3 parts-per-million (ppm), while also reducing 30-silicon to below 1 ppm and removing other impurities. The book also presents the first reported electrically detected magnetic resonance spectroscopy study of the magnetic clock transition in 75-arsenic doped silicon. This is of interest to those developing donor-based qubit systems for quantum technologies as these transitions show reduced sensitivity to otherwise deleterious magnetic field fluctuations. Overall, the thesis represents a significant advance in the state-of-the-art relating to advanced semiconductor platforms for quantum technologies.
