Postdoctoral Research Associate in Scanning Probe Microscopy for Ultrafast Charge Dynamics Oak Ridge National Laboratory in United States

Oak Ridge National Laboratory (ORNL) is recruiting a Postdoctoral Research Associate in Scanning Probe Microscopy for Ultrafast Charge Dynamics at its Center for Nanophase Materials Sciences in the Functional Atomic Force Microscopy Group. The project focuses on 2D material–ferroelectric heterostructures, with an emphasis on understanding fast charge dynamics under slow and fast excitation using advanced high-frequency electrical and optical scanning probe microscopy.

The successful candidate will help develop next-generation AFM-based GHz and THz near-field electrical and optical microscopy modes and use Python scripting to build automated and autonomous experimental workflows. Research activities include probing micro- and nanoscale charge behavior at 2D material/ferroelectric interfaces, studying how polar and ionic dynamics in ferroelectrics affect the electronic response of the 2D material, and contributing to fabrication of the heterostructures. The role also involves collaboration with scientists across ORNL in materials synthesis, heterostructure preparation, theory, and complementary characterization.

Core subject areas: Physics, Materials Science, Electrical Engineering, Chemistry. Relevant technical interests include atomic force microscopy, scanning probe microscopy, optical characterization, microwave/high-frequency measurements, and 2D materials.

Eligibility: Applicants must hold a PhD in materials science and engineering, physics, chemistry, electrical engineering, or a related field completed within the last 5 years. Preferred experience includes instrument development, electronic instrumentation, pump-probe spectroscopy or near-field methods, microwave circuits, advanced AFM techniques such as KPFM/PFM/sMIM, 2D materials, and Python or MATLAB. Strong communication skills and the ability to work independently and collaboratively in a fast-paced research environment are highlighted.

Funding and appointment: The appointment is up to 24 months with the potential for extension, depending on performance and funding availability. ORNL notes competitive pay, benefits, and relocation assistance, but no specific stipend amount is listed.

How to apply: Submit your application through the ORNL jobs portal. Three letters of reference are required and may be uploaded directly or emailed to [email protected] with the position title and number in the subject line. The posting remains open for a minimum of 5 days and then closes when a qualified candidate is identified and/or hired.

Location: Oak Ridge, Tennessee, United States.
