Cap-Exempt H-1B Position — No lottery required
The Electron Microscopy group, one of six scientific groups in the CFN, is composed of seven staff scientists and supports four electron microscopes for characterizing nanomaterials at the atomic scale in-situ and ex-situ (www.bnl.gov/cfn). In this position, you will be a member of the Electron Microscopy group working under the supervision of Dr. Judith C. Yang. Two first-of-its-kind aberration-corrected, monochromated scanning transmission electron microscopes (STEM) optimized for electron-energy loss spectroscopy (EELS) with sub-Angstrom spatial resolution will soon be added to the CFN. With installation expected in 2025, the first EELS-STEM will be an ultra-low KeV STEM for low Z, radiation-sensitive, 2-dimensional, and quantum materials. The second EELS-STEM will be an ultra-high vacuum environmental STEM capable of a pressure range of 10-9 to 1 or 10 Torr at the sample area, with expected installation in 2026. The CFN also houses forefront surface science equipment and synchrotron-based X-ray probe tools within the National Synchrotron Light Source II (NSLSII) for multi-modal investigations. The CFN is seeking an exceptional and creative scientist with outstanding expertise in the instrumentation development and application of advanced scanning transmission electron microscopy and spectroscopy within research areas relevant to energy security, such as heterogeneous catalysis, oxidation/corrosion, and battery materials; microelectronics; and/or quantum materials. Your expertise and strong interest in hardware optimization of cutting-edge STEM as well as in a wide range of forefront electron microscopy and spectroscopy techniques is strongly preferred, especially in cutting-edge electron energy loss spectroscopy (EELS), and you have significant interest in situ and operando microscopy. In this position, you will bear the primary responsibility for optimizing these two-incoming aberration-corrected monochromated STEMs and develop instrumentation science to be at
