Oak Ridge National Laboratory is seeking a Postdoctoral Research Associate to use advanced scanning probe microscopy for the development and application of multiscale excitonic probes to study buried interfaces in monolithic 3D heterogeneous integration (M3D HI) systems, with a particular emphasis on vertically stacked 2D/3D semiconductor heterostructures.
Requirements
- A PhD degree in materials science and engineering, physics, chemistry, electrical engineering, or a related field completed within the last 5 years.
- Previous experience/knowledge in one or more of the following areas: nanoscale optical spectroscopy techniques such as photoluminiscense, electroluminescence, cathodoluminescence-SEM and/or near field optical microscopies (SNOMs).
- 2D materials
- materials for microelectronics
- Proficiency in surface and interface characterization using atomic force microscopy.
- Knowledge of exciton dynamics, charge transport, or interfacial phenomena in low-dimensional systems.
- Experience in materials characterization techniques such as Raman and scanning electron microscopy.
- Data analysis skills using Python, MATLAB, or similar platforms.
Responsibilities
- Conduct materials research using combined photonics/scanning probe microscopy techniques.
- Advance capabilities for specialized scanning probe microscopy methods
- Work as part of a dynamic team conducting research that advances and develops cutting-edge characterization capabilities to improve our understanding of interfaces and defects in low-dimensional heterostructures.
- Present and report research results and publish scientific results in peer-reviewed journals in a timely manner.
- lead experimental efforts using advanced nanoscale optical and scanning probe techniques—including spatially and temporally resolved photoluminescence, electroluminescence, and a strong focus on photoinduced force microscopy (PiFM)—to investigate exciton dynamics, charge transfer, and interfacial disorder.
- designing experiments, preparing and characterizing samples, analyzing data from complementary techniques such as scanning microwave impedance microscopy, Kelvin probe force microscopy, and cathodoluminescence, as well as collaborating with theorists for data-model integration.
- play an integral role in the development of PiFM and closely collaborate with other scientists across the network of NSRCs for synthesis, device fabrication, theoretical calculations, and other characterization methods, as well as across multiple CNMS groups and divisions at ORNL.
Other
- Ensure compliance with environment, safety, health and quality program requirements.
- Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace – in how we treat one another, work together, and measure success.
- Excellent written and oral communication skills.
- 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.
