Postdoctoral Appointee - Transmission Electron Microscopy
Job posting number: #7058370 (Ref:668231)
Posted: July 12, 2019
Job DescriptionWe are seeking a postdoctoral appointee to join our scanning / transmission electron microscopy (S/TEM) lab at the Center for Integrated Nanotechnology (CINT) at Sandia National Laboratories (New Mexico). The focus of the laboratory is quantitative in-situ TEM studies of nanostructured materials and and cryo-focused ion beam (FIB) preparation of liquid-solid interfaces for chemical and structural mapping in the S/TEM. We are looking for a highly motivated candidate with a strong background in electron microscopy characterization and analysis techniques, preferably with some experience with FIB, cryo-TEM, and/or in-situ S/TEM. This position will be focused on the study of liquid-solid interfaces that will utilize the majority of transmission electron microscopy techniques available, some in combination with in-situ imaging/diffraction. The majority of the work will be looking at energy storage materials, such as battery electrodes in contact with electrolytes. Sample preparation techniques for these studies will include: clean room preparation, focused ion-beam, atomic layer deposition, electron beam lithography, metal deposition, electrochemical etching. Relevant electron microscopy techniques to be used in this work include: scanning electron microscopy (SEM) characterization, electron backscattered diffraction (EBSD), high resolution imaging (HR-TEM), precession electron diffraction (PED), energy filtered TEM imaging (EFTEM), energy dispersive x-ray spectroscopy (EDS), electron energy loss spectroscopy (EELS), STEM (with mapping in EDS and EELS), and data/image processing. All equipment/resources are provided within our center. The candidate will be working closely with advisor to prepare samples and to conduct the in-situ measurements and analyze the complementary data. The Cryo-FIB and cryo-TEM are currently being installed in our facility, therefore, we have many experiments planned to produce a wealth of publications over a two-year period. The postdoctoral candidate will engage in original research in many areas of in-situ TEM, including new capability demonstration.
+ You have, or are pursuing a PhD in physics, materials science, chemistry or a related field and you have a bachelor’s in science, technology, engineering or mathematics (STEM) + You possess experience with Transmission Electron Microscopy + You have demonstrated accomplishments in research, as evidenced by publications in peer-reviewed journals and presentations at scientific conferences
+ Demonstrated creativity and highly developed problem solving skills + Background includes crystallography + Excellent verbal and written communication skills + Experience in working on multiple projects simultaneously. High motivation to write manuscripts and present at conferences. Programming/software experience with Python, Mathematica, Matlab, Digital Micrograph, LabView, JEMS, and/or QSTEM + Well-developed skills in one or more of the following areas are desired:
- Nanobeam Electron Diffraction
- Precession Electron Diffraction
- HR STEM
- X-ray Energy Dispersive Spectroscopy Mapping
- Electron Energy Loss Spectroscopy Mapping
- TEM Tilt-Series
- TEM Tomography
- In-situ liquid-cell imaging
- In-situ EELS & EFTEM
Department 1881 – Nanostructure Physics – is one of two departments at Sandia that are a part of The Center for Integrated Nanotechnologies (CINT). CINT is a Department of Energy/Office of Science Nanoscale Science Research Center operating as a national user facility devoted to establishing the scientific principles that govern the design, performance, and integration of nanoscale materials. Through its core facility in Albuquerque and gateway facility at Los Alamos, CINT provides users from academia, industry, and government labs, open access to the tools and expertise needed to explore the continuum from scientific discovery to the integration of nanostructures into the micro- and macro world. CINT is an equal partnership between Sandia National Laboratories and Los Alamos National Laboratory.
Sandia National Laboratories is the nation’s premier science and engineering lab for national security and technology innovation, with teams of specialists focused on cutting-edge work in a broad array of areas. Some of the main reasons we love our jobs: + Challenging work withamazingimpact that contributes to security, peace, and freedom worldwide + Extraordinary co-workers + Some of the best tools, equipment, and research facilities in the world + Career advancement and enrichment opportunities + Flexible schedules, generous vacations,strongmedical and other benefits, competitive 401k, learning opportunities, relocation assistance and amenities aimed at creating a solid work/life balance* _World-changing technologies. Life-changing careers._ Learn more about Sandia at: http://www.sandia.gov *These benefits vary by job classification.
This position does not currently require a Department of Energy (DOE) security clearance. Sandia will conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Furthermore, employees in New Mexico must pass a U.S. Air Force background screen for access to Kirtland Air Force Base. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, resulting in the inability to perform the duties assigned and subsequent termination of employment. If hired without a clearance and it subsequently becomes necessary to obtain and maintain one for the position, or you bid on positions that require a DOE security clearance, a pre-processing background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance must be U.S. citizens. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.
All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status. : This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia's discretion up to five additional years. The PhD must have been conferred within five years prior to employment. Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance.
