Description
Silicon is a common material used in the make up of hybrid quantum systems and semiconductor devices, and is often implemented at low temperatures for quantum technologies, in particular in the isotopically pure form of Si-28. The absence of nuclear spins in such a sample make it an ideal system to realise a multitude of solid state devices based off implanted impurities, including clocks. Electromagnetic diagnostics have been conducted at milliKelvin temperatures, yielding important results for the future development of systems based off this difficult to obtain material. Namely, the importance of surface losses and their removal, the observation of a freeze-out of a conduction mechanism below 1 K and initial observations of narrow bandwidth impurity dopants are reported.
