Scanning Tunneling Microscopy Jobs (NOW HIRING)

This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience Program (PREP). NIST recognizes that its research staff may want to collaborate with researchers at academic institutions on specific projects of mutual interest and, therefore, requires those institutions to be recipients of a PREP award. The PREP program involves staff from a wide range of backgrounds conducting scientific research across various fields. Individuals in this position will perform technical work supporting the collaboration's scientific research.
Research Title: Scanning probe instrumentation and metrology specialist
The work will entail: This work is on the frontier of experimental condensed matter physics, and combines several experimental modalities, including scanning tunneling microscopy, atomic force microscopy, electron transport, and electron spin resonance.
