What are the responsibilities and job description for the Spin manipulation and metrology specialist position at Physics World?
Job Details
Spin manipulation and metrology specialist
The Nanoscale Device Characterization Division of the Physical Measurements Laboratory of the National Institute of Standards and Technology has opportunities for research studying manipulation of atomic spin systems. These systems include adatom, molecules and dangling bond structures on surfaces. Experiments will be carried out at dilution refrigerator temperatures using multi-modal scan probe measurements to probe and manipulate the spin systems. Experiments will be done with and without a magnetic field. Electron spin resonance will br]e done with scanning tunneling microscopy on adatom and molecular systems. Interested people who have substantial experience with atom spin manipulation, electron spin resonance, time-domain measurements, multi-mode scanning probe measurements and dilution refrigerator operation are encouraged to explore these opportunities. This project will be carried out at NIST-Gaithersburg and is expected to last for 2-3 years. People interested in joining should submit a CV and letter of interest.
Required Education: PhD in experimental physics
