Postdoctoral Appointee – Epitaxial Oxide Nanostructures Quantum Information Argonne Nationa

The Center for Nanoscale Materials (CNM) at Argonne National Laboratory seeks a highly motivated postdoctoral researcher to join a multidisciplinary team advancing quantum information science through the design and synthesis of nanoscale epitaxial oxide thin films. This position supports a three-year Laboratory Directed Research and Development (LDRD) project focused on developing scalable photonic platforms for hybrid quantum systems. The role offers a unique opportunity to engage in advanced materials synthesis, nanofabrication, and multimodal characterization using Argonne’s world‑class resources—including the Autonomous Sputter Beam Epitaxy system, the QuEEN‑M electron microscopy platform, and synchrotron X‑ray beamlines at the Advanced Photon Source.

This is an outstanding opportunity for candidates interested in the intersection of complex oxide epitaxy, quantum information, and nanophotonic to contribute to high‑impact science at a national user facility.

• Develop and optimize epitaxial growth of complex oxide nanostructures, especially ferroelectrics, via solid‑phase epitaxy (SPE)
• Perform thin‑film and device characterization across structural (XRD, AFM, SEM, XPS, TEM), optical, cryogenic, and synchrotron X‑ray environments
• Fabricate photonic and metamaterial structures using advanced nanofabrication tools (e.g., lithography, dry etching)
• Contribute to the development and testing of electro‑optic (EO) devices integrated with photonic and microwave platforms
• Collaborate within a multidisciplinary team across CNM, the Advanced Photon Source (APS), Materials Science Division (MSD), and Quantum Information Science (QIS) programs
• Disseminate results through high‑impact publications and presentations at internal and external meetings

• Recent or soon‑to‑be‑completed Ph.D. in Physics, Materials Science, Electrical Engineering, or a related field
• Hands‑on experience in epitaxial thin‑film growth and characterization (oxides preferred), using sputtering (preferred), PLD, or MBE
• Proficiency in thin‑film characterization tools such as XRD, AFM, SEM, XPS, TEM, etc.
• Experience with nanofabrication, particularly lithography and thin‑film processing
• Strong background in ferroelectrics, photonics, or solid‑state materials
• Demonstrated ability to work independently and collaboratively in a multidisciplinary environment
• Strong written and oral communication skills
• Ability to model Argonne’s core values of impact, safety, respect, integrity, and teamwork

• Familiarity with synchrotron‑based X‑ray techniques and electron microscopy
• Experience with optical characterization and EO device testing
• Background in quantum devices, nonlinear optics, or microwave photonics
• Working knowledge of simulation tools such as COMSOL or Lumerical for electro‑optic modeling

• Data analysis using Python
• Experience with autonomous or AI‑assisted synthesis workflows
• Familiarity with quantum transduction or quantum information science

• Cover Letter describing research experience and fit for the role
• Contact information for three references
