What Your Job Will Be Like: re you looking to be a member of a dynamic research team? You can join our team of scientists and researchers at Sandia’s Ion Beam Laboratory and make a difference!We are seeking a Postdoctoral Appointee with expertise and interest in the experimental study of applying machine learning (ML) tools for advanced fabrication of semiconductor materials and devices including wide-bandgap materials such as diamond, SiC, GaOx, GaN, AlGaN, etc… using ion and electron beam irradiation coupled with automated decision-making tools. In this role, you will collaborate with a multidisciplinary team including both internal Sandians and external collaborators.On any given day, you may be called on to: + Collaborate with diverse groups working with a wide array of predictive modeling, device fabrication and in-house material/device testing capabilities including in-situ techniques such as electron and ion beam induced charge collection (EBIC and IBIC),transmission electron microscopy (TEM), electrical device characterization, deep level transient spectroscopy (DLTS), photoluminescence (PL), electroluminescence (EL) and transient microwave reflectance (TMR) + Work on advanced fabrication projects using pioneering focused ion beam technologies in best-in-class labs, that include studies of diamond defect center formation (NV, SiV, GeV, SnV, etc…) for quantum sensing, low-energy ion implantation for material modification, single photon sources and distributed quantum information processing; as well as novel defect center device formation in 2D and ultra-wide bandgap materials including hBN, GaN, etc. + Generate research publications and present at leading technical conferences Qualifications We Require: + You have, or are pursuing, a PhD in Physics, Chemistry, Materials Science, Electrical Engineering, Software Engineering, or related field and possess a bachelor's degree in science, technology, engineering or mathematics (STEM) + Strong scientific background as evidenced by a history of publication of results in peer-reviewed professional journals and presentations at appropriate scientific conferences + Able to acquire and maintain a DOE Q-level security clearance Qualifications We Desire: + Research background with experimental tools focused on material characterization, semiconductors devices, semiconductor device physics, density functional theory (DFT) and/or kinetic Monte Carlo (KMC) modeling of materials and their optical and electrical properties + Experience using probes, ions, or electrons for materials analysis, modification and/or radiation effects testing + Experience with programming languages such as Python, MATLAB, LabView, Java/JavaScript, C++, or experience with software-hardware interaction + Superb analytical skills, upbeat, hard-worker passionate about problem solving About Our Team: The Radiation-Solid Interaction Department operates the Ion Beam Laboratory (IBL). This innovative facility houses 7 major accelerators: a 6 MV Tandem, a 3 MV Pelletron, a 1 MV Tandem, a 400 kV implanter, 35 kV Helium Ion Microscope and both a 35 kV and 100 kV nanoimplantation system with mass velocity filter focused ion beam with <10nm spot sizes. The IBL engages in three major research thrusts: + Understanding the performance of materials in radiation environments. These projects impact the performance of microelectronics in space and other hostile environments, as well as cladding materials in nuclear reactor and storage environments. + Developing and applying novel ion beam techniques to precisely measure materials compositions. Applications in this area include mapping hydrogen isotopes in fusion wall material and measuring the composition of thin complex materials such as transition metal oxides. + Exploring the materials science of defects in solids. This broad area includes single ion implants for quantum applications, anomalous grain growth in nanograined materials, hydride formation under irradiation, and nanomechanical responses of materials. In each thrust the department provides unrivaled capabilities to multidisciplinary teams with an interest in publishing high quality research and applying the results to problems of national interest. Our team is committed to nurturing environment 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 us and work towards your goals while making a difference!

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 need to 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: 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. Position Information: 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.
