Requisition Id 5828
We are seeking a postdoctoral research associate who will focus on growth of ferroic thin films by pulsed laser deposition and characterization of polar properties of the grown films utilizing novel scanning probe microscopy (SPM) approaches, primarily in ultra-high vacuum systems. This position resides in the Functional Atomic Force Microscopy Group within the Nanomaterials Characterization Section at the Center for Nanophase Materials Sciences (CNMS), in the Physical Sciences Directorate at Oak Ridge National Laboratory (ORNL). This position focuses on the controlled synthesis of polar oxide heterostructures and will include imaging via scanning tunneling microscopy and functional property characterization with atomic force microscopy with automated spectroscopy. There will be a strong emphasis on tying experimental results to theoretical calculations via novel machine learning and data analytics approaches. A focus of the effort will be to better understanding driving forces of polar behavior in disordered materials, including canonical relaxor ferroelectrics, via careful introduction of disorder through chemical and field gating, with automated measurements assisting acquisition of high volumes of relevant data.
- Grow oxide films using pulsed laser deposition and characterize their surface and bulk structures
- Measure functional properties of the polar films, including piezoelectric, ferroelectric, and electrical transport via scanning tunneling microscopy, conductive atomic force microscopy, and piezoresponse force microscopy
- Work with, and improve on, automated approaches for spectroscopy developed at the CNMS for characterization of the grown films
- Elucidate the surface structure utilizing reflection high energy electron diffraction and low energy electron diffraction of the grown surfaces
- Publish work in high-impact journals in a timely manner
- Present and report research results in peer-reviewed journals in a timely manner
- Ensure compliance with environment, safety, health and quality program requirements
- Maintain strong dedication to the implementation and perpetuation of values and ethics.
- A PhD in physics, materials science or related discipline completed within the last 5 years
- Background in synthesis of oxide materials
- Experience in use of scientific instruments for characterization in ultra-high vacuum environments
- Experience with pulsed laser deposition of oxide thin films
- Experience with use of atomic force microscopy and scanning tunneling microscopy to understand electronic properties of materials
- Strong background in ferroic and/or polar materials
- Experience with programming in python and LabView
- Excellent written and oral communication skills and the ability to communicate to an international, scientific audience
- Excellent record of productive and creative research as demonstrated by publications in peer-reviewed journals
- Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory
- Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs
