Postdoctoral Fellow (PREP0004401)
The American Ceramic Society, Gaithersburg, MD, United States
Position Title
PREP Research Associate – CHIPS Funded Project
Program Overview
This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience Program (PREP). NIST recognizes that its research staff may want to collaborate with researchers at academic institutions on specific projects of mutual interest and, therefore, requires those institutions to be recipients of a PREP award. The PREP program involves staff from a wide range of backgrounds conducting scientific research across various fields. Individuals in this position will perform technical work supporting the collaboration's scientific research.
Research Title
Digital Twins for Atomic Layer Deposition Processes
Project Description
The Chemical Sciences Division of the National Institute of Standards and Technology (NIST) is seeking a postdoctoral researcher to join a multi-disciplinary team of scientists working on advanced modeling of atomic layer deposition (ALD) processes. The project will develop a suite of in-situ metrology tools to quantify mass transport processes occurring during thermal ALD. Metrology data will support the development of computational fluid dynamics (CFD) and machine learning (ML) models of transport and surface reaction processes, with the ultimate goal of producing validated digital twins for thermal ALD processes. The project team includes experts in vapor phase deposition processes, in-situ optical metrology, micro-electromechanical system (MEMS) design, numerical modeling, and machine learning. NIST maintains unique facilities for the development and application of fast and sensitive in-situ diagnostics for vapor phase deposition processes. Multiple research-grade ALD systems dedicated to oxide, metal, and sulfide film deposition are available, as well as optical measurements spanning the UV and mid-IR wavelengths tailored for surface and gas-phase processes.
Key Responsibilities
Operate and maintain multiple ALD system and custom in-situ optical setups
Perform temporally- and spatially-resolved optical measurements during ALD
Use and analyze optical process data to validate transport models
Publish findings in peer-reviewed scientific journals and present at conferences
Qualifications
Hands-on expertise in the design and assembly of research-grade ALD reactors
Expertise in building and maintaining custom lab instrumentation
Expertise in vapor phase deposition processes such as ALD
Safe operation and maintenance of ALD systems
Operation of in-situ process diagnostics, including custom optical setups
Knowledgeable in vapor transport mechanisms, precursor chemistry, and process development/optimization applicable to ALD
Ph.D. or equivalent experience in chemistry, physics, materials science, or related field
Strong written and oral communication skills
Ability to work as part of a team and independently
Citizenship
U.S. Citizen Preferred
Equal Employment Opportunity Statement
The Johns Hopkins University is committed to equal opportunity for its faculty, staff, and students. To that end, the university does not discriminate on the basis of sex, gender, marital status, pregnancy, race, color, ethnicity, national origin, age, disability, religion, sexual orientation, gender identity or expression, veteran status or other legally protected characteristic. The university is committed to providing qualified individuals access to all academic and employment programs, benefits and activities on the basis of demonstrated ability, performance and merit without regard to personal factors that are irrelevant to the program involved.
Background Check
The successful candidate(s) for this position will be subject to a pre-employment background check including education verification.
