What Your Job Will Be Like: The Ion Beam Laboratory (IBL) at Sandia National Laboratories is seeking a mid-career staff scientist with expertise and curiosity about exploring basic science research using electron, ion, and neutron irradiation. The IBL combines electron, ion and neutron irradiation with a suite of novel analytical capabilities such as in-situ transmission electron microscopy (TEM) and in-situ scanning electron microscopy (SEM), 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), etc…You will use these tools and more to explore functional materials, radiation effects in semiconductor materials and devices, and investigate new avenues for doing material science with defect engineering from macro- to nano-scale. Join our multidisciplinary team to perform pioneering experiments and modeling based around Sandia’s ion accelerator capabilities. Sandia Job Title: R&D Physics. This position is expected to support these key areas of research at the Ion Beam Laboratory: + In-situ operation of the combined heavy ion and TEM/SEM end-stations. These instruments are unique for unprecedented exploration and understanding of radiation induced defects in a wide range of materials systems. Additionally, a wide selection of holders and accessories for these tools expand their capabilities to include nanomechanical straining, micro-indentation, laser heating, experiments at various temperatures, electrical measurements, liquid-cell electrochemistry, and others. + Ion beam-based nanoscale fabrication and characterization of radiation effects in materials and devices using a range of focused ion beam implantation capabilities from two mass separated focused ion beam systems with <10 nm resolution to multiple high energy microbeams with 150 nm to 1 mm resolution. These systems represent a set of unique capabilities found only at Sandia National Laboratories enabling innovative research. + Ion beam irradiation of semiconductor materials 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 questions surrounding radiation induced defects in a wide range of semiconductors from Si, SiC, GaN, AlGaN, etc. + Generation of 2.5 MeV and 14 MeV monoenergetic neutron for both radiation effects testing and neutron detector calibrations supporting national security mission needs. On any given day, you may be called on to: + Develop new research programs using 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 Qualifications We Require: + PhD in Physics, Chemistry, Materials Science, Electrical Engineering, or a related field with 5 or more years of relevant national lab, academic or industrial experience + A history of publications in peer-reviewed professional journals and presentations at appropriate scientific conferences + Experience in leading research teams comprised of scientists, postdoctoral scholars, and graduate students + Experience with nanoscale materials characterization and high-resolution transmission electron microscopy and scanning electron microscopy + Experience using ion beams (1keV – multi-MeV) for materials analysis, modification and/or radiation effects testing + Able to acquire and maintain a DOE Q-level security clearance Qualifications We Desire: + Master’s Degree or Ph.D. in Physics, Materials Science, Electrical Engineering, or related field + Research background with in-situ TEM/SEM experiments for ion irradiation and implantation and/or nanoscale mechanical property testing including in-situ heating, liquid-cell electrochemistry, electrical characterization, diffraction and defect analysis, tomography, and ultrafast or dynamic TEM + Experience leading research projects evidenced by track record of acquiring funding from either internal or external agencies and conducting independent research + 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 Interaction Department operates the Ion Beam Laboratory (IBL).
