Our Vision To help strengthen U.S. competitiveness in key industries, we aim to be a leader in the science and application of low-temperature plasmas, including nanofabrication that enables microelectronics and quantum technologies of tomorrow, and processes to help sustainably decarbonize multiple industries. Microelectronics PPPL is working with the semiconductor industry to develop new ways to fabricate capable, efficient, and cost-effective chips. Industry goals include a major expansion in the type and structure of the materials to be used, which must be implemented with atomic-scale precision. The Lab’s expertise in low-temperature plasmas, which are used in nearly half of all steps in fabricating computer chips, are helping transform what has been a black-box, Edisonian approach into one based on scientific understanding and engineering control. Our Partners We're partnering with Lam to simulate a key step in atomic-scale chip fabrication, an increasingly critical process that aims to remove single atomic layers from silicon surfaces, one at a time. Our partnership with Samsung has focused on the etching of computer logic and memory patterns on microscopically thin layers of chips — key applications of plasma in chip fabrication. For Applied Materials, we're developing new plasma diagnostics and modeling tools for key processing steps such as atomic-scale etching in microchip manufacturing. Quantum Information Science (QIS) Our researchers are exploring the use of diamond-based materials to create alternatives to silicon in the fabrication of microchips and could enable a wholly new type of chip relying on quantum bits, or “qubits,” that take the place of standard bits used in silicon-based computers. Qubits could make possible quantum computers that would be far faster and more powerful than computers today. A key goal of our Lab is to enhance qubit production with plasma to advance quantum device fabrication. Photoluminescence with above-bandgap excitation in layered diamond Bringing the World of Quantum Physics into Light With Princeton University, we're currently developing a next-generation diamond sensor with capabilities that range from imaging single molecules to guiding aircraft by detecting slight anomalies in the Earth’s magnetic field. This work is supported by a highly competitive three-year, $5.2-million award from the Department of Energy. Sustainability Science We're applying our experimental and computational strengths in plasma, engineering, and electrochemical and materials science to contribute to a Net-Zero America. Our goal is not only to contribute to basic science research, but also bring discoveries to deployment. Electromanufacturing In alignment with many of the Department of Energy’s Earthshot initiatives, we're committed to advancing low-carbon technologies for a sustainable and competitive U.S. manufacturing industry. Our researchers are investigating ways to replace fossil fuels with electricity, including plasmas, in industrial processes. Electricity could more sustainably produce chemicals like hydrogen, ethylene, and ammonia; steel and cement; and even capture and chemically transform carbon dioxide and recycle plastics. Ongoing Projects Use of plasma to enhance conversion of natural gas (methane) to hydrogen Use of plasma or electric heating to produce ammonia from air and hydrogen Use of electricity to produce useful chemicals and fuel from carbon dioxide Solar Radiation Management Reflecting the sun's energy back to space could help cool the planet. Our researchers aim to study how clouds, light, and aerosols — small particles in the air — interact in controlled laboratory conditions, so that we can safely determine the science underpinning such cooling strategies. Ongoing Projects Better understanding of aerosol-light-cloud dynamics Research and discovery around new, environmentally benign, scalable aerosol materials that may feature desirable properties for solar radiation management campaigns. This includes stratospheric aerosol injection and cirrus cloud thinning Meet the Team Emily Carter Associate Lab Director for Applied Materials and Sustainability Sciences Phil Efthimion Deputy Associate Lab Director for Applied Materials and Sustainability Sciences Mark Martirez Staff Research Scientist and Deputy Advisor for Sustainability Sciences Electromanufacturing Igor Kaganovich Principal Research Physicist, Deputy Head, Theory Department Solar Radiation Management Yevgeny Raitses Managing Principal Research Physicist Microelectronics David Graves Professor of Chemical and Biological Engineering, Princeton University Quantum Materials and Devices Connect with us Looking to learn more?
