Job Description

The Applied Optical and Plasma Sciences Department is seeking a postdoctoral researcher for creating and using next generation implementations of vibrational spectroscopies (e.g., Raman and FTIR) One aspect of this work will entail creating new spectroscopic implementations by integrating optical spectroscopic capabilities into existing experimental systems to permit in-situ interrogation of samples under complex and evolving environments. A second aspect of this work leverages vibrational spectroscopy techniques to evaluate materials for a variety of performance and compositional attributes requiring extensive knowledge of design of experiments and data analysis methods to characterize fundamental properties and changes in fundamental properties of glasses, ceramics, polymers, microelectronics, nanomaterials, and novel 2D-materials. To this end, combined in-situ characterization tools (Raman, TEM, SEM, etc.) will be developed to investigate materials in complex and overlapping experiments. The extreme environmental stressors that will be explored include: thermal, mechanical, electrical biasing, irradiation, liquidous, and gaseous environments. These systems will be utilized to investigate the fundamental mechanisms driving material alterations in coupled environments. A portion of the effort will be invested in collaborating with external users from premier domestic and international universities. A second component of the position will be leveraging vibrational spectroscopic techniques to identify material compositions, including minor impurities, to generate an understanding of material performance over an extensive range of harsh environmental conditions including fundamental failure modes. Taken together, the research effort will extend basic understanding of material-photon-phonon interactions and multi-physical phenomena while also elucidating the means by which such interaction can be leveraged for function. You will be expected to effectively contribute towards team efforts to publish and present their research results in leading journals and conferences. Key functions of this role include, but are not limited to: + Publication of scientific results and participation in the scientific community, including international conferences and workshops + Material characterization including performance metrics, failure analysis, stress and strain measurements, and impurity analysis including quantification + Design of experiments to quantify the aforementioned material attributes + Design, build, and development of new in-situ characterization tools

+ You have or are pursuing a PhD. in Physics, Chemistry, Materials Science or Engineering, or closely related discipline and have a bachelor’s in science, technology, engineering or mathematics (STEM). + Your background includes experience in using and developing vibrational spectroscopic techniques to identify, examine, and understand material properties and performance + Able to obtain and maintain a DOE Q-level security clearance

+ The motivation and ability to tackle technical problems independently + Good communication and interpersonal skills fostering effective scientific collaborations with a diverse population of researchers + Proficiency in COMSOL, MATLAB, GRAMS + Experience in design of experiments to provide data analysis, statistics, and use of multivariate analysis techniques, e.g. Principle Component Analysis + Experience with theory and experiments in Raman, infrared (FTIR, ATR, etc.), and Brillouin spectroscopies, including polarization-resolved measurements + Background in spectroscopic analysis of glasses, ceramics, polymers, silicon, PZT and other piezoelectric materials, optical-based stress and strain measurements, various nitrides, nanotubes, and thin films.

Department Description:

The department has three main thrust areas: Laser and Optical Diagnostics, Low Temperature Plasma Physics, and Thermal Characterization of Materials. The Laser and Optical Diagnostics thrust conducts innovative research and application development in LIDAR remote sensing, laser sources and characterization, and optical spectroscopy providing unique, real-time, non-contact, in-situ optical diagnostic capabilities. The Low Temperature Plasma physics thrust investigates a range of phenomena from fundamental plasma physics to the application of plasma science for understanding device operation. A tightly coupled group of experimental and computational physicists develop novel experimental diagnostics and advanced computational models targeting plasma-surface interactions, arc discharge (vacuum to high pressure), and complex plasma chemistry. The Thermal Characterization thrust researches the fundamental thermal properties and decomposition products and pathways of a wide variety of materials experiencing an expansive range of environments. This work entails both state-of-the-art diagnostics as well as developing custom diagnostics and techniques to provide information on the underlying science of thermal behaviors of materials.

Security Clearance:

Position requires a Department of Energy (DOE) Q-level security clearance. Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment must be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. 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. Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.

EEO Statement:

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.
