Post-Doc Position in


sThe ESR-STM lab at QNS is looking for several postdoctoral candidates. One opening is focused on revealing the spin structures of molecules and nanostructures with sub-nm resolution using the recently developed ESR-STM technique based on a Unisoku 3-He STM. QNS is one of the few labs around the world that have demonstrated ESR STM at the single atom level. In this project we want to utilize ESR-active atoms on surfaces as quantum sensors to detect the magnetic properties of nearby ‘unknown’ species.

A second and possibly third postdoctoral position is available utilizing home-built ESR STM systems. One system is built inside a dilution fridge which operates below 10 mK and a second one in a closed-cycle Joule-Thomson system. These two systems will offer temperatures from 10 mK to 40 K as well as magnetic fields in several vector geometries. Candidates for these positions should have some experience and a strong interest in developing home-built instrumentation. The research goals include ESR STM as well as quantum-coherent manipulation of spins on surfaces for possible quantum computing applications.
