Applied Materials and Sustainability Sciences (AMSS)







The U.S. Department of Energy’s Princeton Plasma Physics Laboratory is now using its expertise in plasma to serve as an economic driver of innovation — using novel plasma technologies to produce computer chips, advance quantum computing techniques and contribute to a net-zero world.

This video features Emily Carter, Gerhard R. Andlinger Professor in Energy and the Environment at Princeton University and associate laboratory director of applied materials and sustainability sciences and senior strategic advisor for sustainability science at PPPL; Nirbhav Chopra, a graduate student in astrophysical sciences; and John Mark P. Martirez, staff research scientist and deputy advisor for sustainability science. Special thanks to Susan Reslewic Keatley '99 for helping contribute to the questions asked during this interview.

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.

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.
