Accurate Mapping of Thermal Properties at the Nanoscale

Ongoing
Continuous advances in the performance and functionality of semiconductor devices have been driven by scale reduction, incorporation of new and nanomaterials, and by heterogeneous integration (HI). However, such scaling and integrated architecture has rendered existing thermal metrology inadequate

Diamond NV Center Magnetometry

Completed
A flaw in a crystal might not be an intuitive choice for a measurement tool, but the nitrogen-vacancy (NV-) defect in diamond is something special. Using light, we prepare the NV- center’s the quantum spin state, it interacts with magnetic fields, and we read out the resulting spin state through
