Any concerns about the ability to meet this requirement should be directed to HR Solutions at (505) 284-4700. : The Ion Beam Laboratory (IBL) is seeking a hard working staff scientist with expertise and curiosity about exploring basic science research in the field of in-situ transmission electron microscopy (TEM) and in-situ scanning electron microscopy (SEM) in conjunction with ion irradiation. You will use these capabilities to explore radiation effects in semiconductor materials and devices, characterize structural materials, and investigate new avenues for doing material science with defect engineering and nanomechanics. Join our multidisciplinary team to perform innovative experiments and modeling based around Sandia’s ion accelerator capabilities. This position will support these key areas of research at the Ion Beam Laboratory: + In-situ operation of the combined heavy ion and TEM/SEM end-stations located on the 6 MV Tandem Accelerator. These instruments have capabilities for unprecedented exploration and understanding of radiation induced defects in a wide range of materials systems. Additionally, a wide selection of holders and accessories on these tools expand the imaging capability to include nanomechanical straining, micro-indentation, laser heating, experiments at various temperatures, electrical measurements, liquid-cell electrochemistry, and others. + Ion beam irradiation of semiconductor materials to aid a series of ongoing projects 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 Ion Beam Laboratory 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. On any given day, you may be called on to: + Develop new research programs using the capabilities of Sandia’s Ion Beam Laboratory to address critical mission needs. For example, the development of new and improved experimental and modeling capabilities 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 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 techniques such as deep level transient spectroscopy (DLTS), photoluminescence (PL), electroluminescence (EL), transient microwave reflectance (TMR), electron and ion beam induced charge collection (EBIC and IBIC) + Generate research publications and present at leading technical conferences Sandia Job Title: Research & Development S&E Physics

+ Master's or Ph.D. in Physics, Materials Science, Electrical Engineering, or a related field with at least 1 year of postdoctoral or industrial experience + A history of publication of results in peer-reviewed professional journals and presentations at appropriate scientific conferences + Experience leading research project as evidenced by track record of acquiring funding from either internal or external agencies and conducting independent research + Experience with nanoscale materials characterization and high-resolution transmission electron microscopy and scanning electron microscopy + Able to acquire and maintain a DOE Q-level security clearance

+ PhD 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 + Research background in semiconductors defects effects in devices and materials, semiconductor device physics, and/or TCAD modeling of devices + Experience using ion beams (100keV – multi-MeV) for materials analysis, modification and/or radiation effects testing + 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 + Upbeat, hard working individual who is passionate about problem solving with superb analytical skills and proven interpersonal skills

Department Description:

The Radiation-Solid Interaction Department operates the Ion Beam Laboratory (IBL). This pioneering 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 focused ion beam system with mass velocity filter. Other experimental facilities include focused micro beam lines on all the major accelerators. 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 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 us and work towards your goals while making a difference!
