The Radiation‑Solid Interactions Department at Sandia National Laboratories, which operates the Ion Beam Laboratory (IBL), is seeking a senior physicist scientist with a strong interest and expertise in focused ion beam implantation/irradiation and optical testing using photoluminescence. The successful candidate will explore the creation and characterization of single‑atom‑based devices in wide bandgap materials such as diamond, SiC, etc., silicon CMOS structures, and III‑V devices.

Current projects using focused ion beams include:

• Diamond Defect Center Formation:
  Investigating NV, SiV, GeV, SnV, PbV, and other defect centers for applications in quantum sensing, single‑photon sources, and distributed quantum information processing.
• Novel Defect Center Formation:
  Exploring defect centers in 2D transition metal dichalcogenides (TMDs) and ultra‑wide bandgap materials such as hBN, MOS2, etc.
• Deterministic Seeding of Conductive Filaments:
  Researching TaOx memristive memories and novel magnetic junction memories.
• Single Particle Irradiation Effects in Advanced CMOS Devices:
  Studying localized radiation effects in state‑of‑the‑art CMOS technologies, including FinFET and GAAFET geometries.

This position encompasses both nanofabrication and optical testing of cutting‑edge materials and devices. The role will utilize a range of focused ion beam implantation capabilities including both 100 kV and 35 kV mass‑separated focused ion beam systems. Additionally, you will collaborate with a multidisciplinary team, engaging with both internal and external partners through close connections with the Center for Integrated Technology (CINT) at Sandia and Los Alamos.

• Develop and Utilize Unique Nanoimplantation Systems:
  Use focused ion beam systems that enable the direct writing of nanometer‑scale devices using a variety of ion species and energies, achieving single‑atom device fabrication with resolutions in the tens of nanometers.
• Implement testing of optically active defects:
  Conduct optical characterization of in‑house fabricated single‑atom devices using confocal photoluminescence setups and perform electrical characterization with a low‑temperature probe station.
• Collaborate in a Multidisciplinary Team:
  Contribute to significant advancements in the quantum realm, resulting in multiple high‑impact publications, including articles in prestigious journals such as Science and Nature, as well as several R&D 100 awards for innovative solutions in radiation effects testing.
• Generate Research Publications and Present at Leading Technical Conferences:
  Actively contribute to the dissemination of research findings through publications and presentations at prominent technical conferences.

Due to the nature of the work, the selected applicant must be able to work onsite in Albuquerque, New Mexico. Relocation will be provided for those that qualify.
