Low-temperature plasmas (LTPs) play a central role in advanced materials processing, microelectronics manufacturing, plasma propulsion, and emerging quantum and energy applications. At Princeton Plasma Physics Laboratory (PPPL), we employ a physics-driven, diagnostics-rich experimental approach to understand and control plasma kinetics, plasma– surface interactions, and nonequilibrium chemistry across a broad range of operating regimes. This talk will highlight recent experimental advances in partially magnetized plasma systems, including electron-beam-generated plasmas and crossed-field (E×B) plasmas relevant to plasma propulsion and materials processing. Particular emphasis will be placed on ongoing research aimed at enabling gentle plasma processing of two-dimensional materials for microelectronics and diamond-based platforms for quantum technologies. These efforts are supported by the U.S. Department of Energy through the Princeton Collaborative Low Temperature Plasma Research Facility (PCRF), the Plasma-enabled 2D Materials for Energy-efficient Microelectronics (PlasMat2D) program, and multiple Cooperative Research and Development Agreements (CRADAs) with industry partners. The talk will provide an overview of these projects and their associated advances in plasma and materials science.
