What Your Job Will Be Like: The Ion Beam Laboratory (IBL) at Sandia National Laboratories is seeking a mid-career staff physics scientist with interest and expertise in exploring radiation effects in semiconductor materials and devices using electron, ion, and neutron irradiation. The IBL combines irradiation capabilities with in-situ electrical characterization techniques, including deep level transient spectroscopy (DLTS), photoluminescence (PL), electroluminescence (EL), transient microwave reflectance (TMR), electron and ion beam induced charge collection (EBIC and IBIC), current voltage characterization (IVs), capacitance voltage characterization (CVs) etc. As well as a suite of in-situ analytical capabilities, such as transmission electron microscopy (TEM) and scanning electron microscopy (SEM), enabling state-of-the-art research. You will use these tools and more to explore the fundamentals of radiation effects in semiconductor materials and devices; as well as investigate new avenues for material science with defect engineering from macro- to nano-scale. Join our multidisciplinary team to perform state-of-the-art experiments and modeling based around Sandia’s accelerator capabilities. This position is expected to support these key areas of research at the Ion Beam Laboratory: + Ion beam irradiation of semiconductors using heavy ions to simulate neutron displacement damage and combined ion plus electron exposure to simulate a combined neutron plus gamma environment. These two capabilities allow Sandia’s IBL to provide unprecedented material behavior insight and explore the fundamental science surrounding radiation induced defects in a wide range of classical and modern semiconductor systems from Si, SiC, GaN, AlGaN, and other advanced materials and design concepts + Ion beam-based nanoscale fabrication and characterization of radiation effects in materials and devices. The research will involve using a range of focused ion beam implantation capabilities from focused ion beam systems with <10 nm resolution to multiple high energy microbeams with 150 nm to 1 mm resolution. The combination of these unique capabilities enables state-of-the-art research that can only be found at Sandia National Laboratories On any given day, you may be called on to: + Develop new research programs utilizing the Sandia’s Ion Beam Laboratory capabilities to address critical mission needs. For example, the development of new and enhanced experimental and modeling techniques to understand and predict radiation response in semiconductor materials and devices including high-impact research towards understanding atomistic- and nano-scale phenomena and their influence on material behavior in extreme environments + Perform electron, ion or neutron-based experiments and collaborate with diverse groups working with a wide array of predictive modeling, device fabrication and in-house material/device testing capabilities including in-situ electrical characterization techniques and in-situ material structural characterization + Generate research publications and present at leading technical conferences Due to the nature of the work, the selected applicant must be able to work onsite Qualifications We Require: + Master’s in physics, chemistry, materials science, electrical engineering, or a related field plus at five or more years of relevant national laboratory, academic or industrial experience, or PhD with one or more years of relevant experience + Experience leading research projects evidenced by track record of acquiring funding from either internal or external agencies and conducting independent research + Experience in leading research teams comprised of scientists, technologists, postdoctoral scholars, and/or graduate students + Experience using electron (keV-to-MeV), ion (keV-to-multi-MeV) or neutrons for semiconductor materials or device testing including radiation effects testing and /or materials analysis and modification + Able to acquire and maintain a DOE Q-level security clearance Qualifications We Desire: + A history of publications in peer-reviewed professional journals and presentations at appropriate scientific conferences + Experience with programming languages such as Python, Visual C and LabView or experience with software-hardware interaction + Experience with developing safe operating procedures for potentially high hazard systems and/or operations in a multi-user facility + Superb analytical skills and excellent interpersonal skills About Our Team: The Radiation-Solid Interactions Department consists of a mix of post-doctoral appointees, permanent technical staff and technologists running and maintaining the Ion Beam Laboratory (IBL). We have a vibrant team representing a wide range of backgrounds, skill sets and work styles. The IBL houses 7 major accelerators: a 6 MV Tandem, a 3 MV Pelletron, a 1 MV tandem, a 400 kV implanter, a 30 kV Helium Ion Microscope and both a 35kV and 100 kV mass velocity filtered focused ion beam systems with <10nm spot size on target. Other experimental facilities include micro beam lines on all the major accelerators and a TEM, equipped with gas, fluid, and nanomechanical stages, with in-situ ion irradiation available from both the Tandem and a Colutron source. While our major equipment is typically run by individual technologists, the team works together to develop new capabilities, perform maintenance, and produce great scientific results. The IBL engages in three major research thrusts: (1) 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.(2) 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.(3) 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. Within each research thrust, individual staff develop a deep expertise in relevant subject matter, and our technologists develop unique technical knowledge in instrumentation and data acquisition. Teams are formed using these discriminating and complementary skillsets to collaborate in research that has direct impact on Sandia’s mission areas. Our team and our leadership is committed to nurturing a culture that welcomes people of a broad and diverse backgrounds and perspectives, encourages dialogue and sharing of ideas, and strives for excellence in research. Join us and work towards your goals while making a difference! Posting Duration: 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.
