Job Description

This posting will be open for application submissions for a minimum of seven (7) calendar days, including the ‘posting date’. Sandia reserves the right to extend the posting date at any time. : Our team is 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 solid-liquid 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 focused ion beam (FIB) and in-situ S/TEM experience. This position will study solid-liquid and solid-gas interfaces that will utilize the majority of transmission electron microscopy techniques available, some in combination with in-situ imaging/diffraction. The project will be investigating steel’s microstructural interaction with corrosive environments, including hydrogen gas, identifying failure mechanisms. Sample preparation techniques for these studies will include clean room preparation, focused ion-beam, atomic layer deposition, and electron beam lithography. 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 their advisor to prepare samples and to conduct the in-situ measurements and analyze the complementary data. Bulk sample analysis will be performed in addition to in-situ TEM experiments. The postdoctoral candidate will engage in original research in many areas of in-situ TEM, working with a multi-institution collaborative team.

Required:
+ You have, or are pursuing, a Ph.D. in physics, materials science, chemistry or a related field + Proven accomplishments in research, as evidenced by publications in peer-reviewed journals and professional presentations at scientific conferences + Demonstrated experience in transmission electron microscopy + Experience in crystallography

Desired:
+ Outstanding Interpersonal skills verbal and written + Proven creativity and highly developed problem solving skills We are looking for someone who is highly motivated to publish journal articles and present research at conferences. Well-developed skills in one or more of the following areas are also desired: + Nanobeam Electron Diffraction + Precession Electron Diffraction + Plasma Focused Ion Beam + HR STEM + X-ray Energy Dispersive Spectroscopy Mapping + Electron Energy Loss Spectroscopy Mapping + TEM Tilt-Series + TEM Tomography + In-situ Liquid-Cell TEM + In-situ EELS & EFTEM + Programming experience with Python, Mathematica, Matlab, LabView, JEMS, QSTEM, etc.

Department Description:

The Nanostructure Physics department 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 dedicated 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. Our team is committed to nurturing a culture compatible with a broad group of people and perspectives in accordance with the changing makeup of the workforce. In support of this vision, our center actively recruits applicants from diverse groups of backgrounds and fosters an inclusive community. Join our team and work towards your goals while making a difference! Contact: Katherine Jungjohann, kljungj@sandia.gov

Security Clearance:

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 need to 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 clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to 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. Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals. The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date.

EEO Statement:

All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law. : 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.
