Computational Research Scientist (Two-Dimensional Materials and Low-Pressure Processing Plasma)

Overview

The Princeton Plasma Physics Laboratory (PPPL) is seeking to appoint a Computational Scientist to contribute to the advancement of modeling capabilities and physics research pertaining to using low-temperature plasmas for processing of two-dimensional materials and associated technologies. The primary responsibility of this position involves conducting and facilitating computational modeling of processing of 2D materials by low-temperature plasma for the purposes of scientific discovery and engineering design of these processes. The successful candidate will achieve this objective through the application of density functional theory (DFT) modeling of these processes using ab initio molecular dynamics (MD), and the utilization of machine learning potentials for MD acceleration.
The candidate should have strong practical familiarity with MD simulations and band gap structure calculations of 2D material properties and connection to experimental measurements. Furthermore, the candidate should demonstrate substantial practical knowledge of 2D material properties and techniques employed in plasma processing, coupled with a proven track record of modeling of such discharges. The results will be disseminated to the broader academic and industrial communities, necessitating strong interpersonal and communication skills to cultivate these relationships. Finally, this role will encompass the conceptualization and preparation of novel proposal ideas to secure funding for future research projects.

Responsibilities

Application of ab initio molecular dynamics to low-temperature plasmas for processing of two-dimensional materials and associated technologies. The capabilities will be deployed for optimization of processing techniques of these materials. The candidate will be responsible for contributing to ongoing project on processing of two-dimensional materials based on transit metal dichalcogenides (50%). Defining and delivering on A.I. projects for low-temperature plasmas (20%). Proposal ideation and preparation (10%). Modeling plasma processing for industry partners (20%). Publishing scientific results and dissemination at major international conferences (10%).

Qualifications

• Ph.D. in Physics, Engineering or a related field with core training in low-temperature plasma physics and high-performance computing.
• Minimum 3 years of professional experience in an academic, scientific, or R&D environment.
• A proven track record of publishing original results in peer-reviewed scientific journals.
• Demonstrated collaborative experience within academia and with industry.

Knowledge, Skills, and Abilities:

• Extensive practical experience using first-principles methods to study materials relevant to microelectronics, quantum devices, and plasma assisted processing, including ab initio molecular dynamics and classical molecular dynamics simulations. Strong ability to connect atomistic simulation results to experimentally relevant materials properties and processing outcomes, including defect formation, surface functionalization, selective etching, plasma-induced damage, optoelectronic properties, surface cleaning, and modification of 2D materials
• Practical knowledge of low-temperature plasma processing of materials, including plasma-assisted etching, ion/surface interactions, fluorination, oxygen and hydrogen surface chemistry, plasma activated desorption, and highly selective or self-limiting processes relevant to nanofabrication of microelectronics and quantum-device materials. Ability to develop computational workflows that support optimization of plasma processing conditions and interpretation of experimental observations
• Advanced experience with major electronic structure, molecular dynamics, and quantum chemistry software packages, including VASP, CP2K, Gaussian, Quantum ESPRESSO, LAMMPS, and related atomistic modeling tools.
• Strong record of scientific publication and conference presentation in electronic structure calculations, 2D materials, defects, and plasma-assisted processing of 2D materials. Ability to communicate complex computational results clearly to scientific, engineering, experimental, academic, and industrial audiences.
• Demonstrated ability to work collaboratively in multidisciplinary research environments involving theory, computation, experiment, and industry-relevant materials processing applications. Ability to contribute to proposal ideation, preparation of research plans, development of new computational capabilities, and dissemination of results through peer-reviewed publications, talks, and major international conferences.
