Postdoctoral Appointee - Optical Spectroscopy of Atomic Defects in Heterostructures for Ultra-Dense Digital Memory (Term)

Argonne National Laboratory

Lemont, IL

Job posting number: #7109287 (Ref:414032)

Posted: August 30, 2022

Application Deadline: Open Until Filled

Job Description

The Materials Science Division seeks candidates with a background in spectroscopy of luminescent atomic/molecular systems or defects in solids. Strong interest in interdisciplinary research across atomic physics and condense matter physics is highly desirable. Expertise in laser optics and/or high-precision spectroscopy of light-matter interfaces is required. Prior experience with atomic defect (e.g. rare-earths, color centers in diamond or other semiconductors) optical spectroscopy, cryogenic instrumentation, nano-electronics, or photonics are preferred.

The postdoc scientist will conduct cutting-edge experimental research on high precision laser spectroscopy of optically active rare-earth dopants in oxide or other semiconductor heterostructures synthesized by other team members of this collaborative project. The experimental studies will focus on excited-state dynamics of rare-earth systems and their relaxations via energy transfer to localized traps in the host matrix.

The researcher will need to work very closely and synergistically with the material grower, microscopists and computational scientist to develop an understanding of the energy transfer mechanism, such as excitation/de-excitation, trap/de-trap via a variety of physical processes in the material. The project will also involve fabrication and measurement of novel devices for demonstrating optical read/write operations of an atomic-scale memory via rare-earth dopants

Position Requirements

Ph.D. degree level with 0 to 3 years of experience or equivalent in physics, applied sciences, engineering or a related field is required

The postdoc will work under the supervision of Supratik Guha and Tian Zhong and will be in close collaboration with material science and theory colleagues in the team.
