Postdoctoral Research Associate - Scanning Probe Microscopy for Ultrafast Charge Dynamics
About The Position
The Postdoctoral Research Associate will investigate fast charge dynamics in 2D material–ferroelectric heterostructures under slow and fast excitation. The role involves developing and using high-frequency electrical and optical scanning probe microscopy, including advanced AFM-based GHz and THz near-field microscopy modes, and using Python scripting to establish automated and autonomous experimental workflows. The research will probe micro- and nanoscale charge dynamics across 2D material/ferroelectric interfaces, especially how polar and ionic dynamics in the ferroelectric affect the electronic response of the 2D material. The associate will contribute to fabrication of 2D material/ferroelectric heterostructures and collaborate with ORNL scientists in materials synthesis, heterostructure preparation, theory, and complementary characterization. The position is in the Functional Atomic Force Microscopy Group, Nanomaterials Characterization Section, Center for Nanophase Materials Sciences, Physical Sciences Directorate at Oak Ridge National Laboratory. The appointment may last up to 24 months, with potential extension subject to performance and funding availability.
Requirements
- Ph.D. in materials science and engineering, physics, chemistry, electrical engineering, or a related field, completed within the last five years; all degree requirements must be completed before the appointment starts.
- Ability to obtain and maintain an HSPD-12 PIV badge, or, for eligible foreign national candidates who have not met the U.S. residency requirement, obtain a favorable LSSO risk determination to maintain employment.
- Submit three letters of reference when applying.
