PNNL News Today
In a significant move to bolster the nation’s technological infrastructure, a research team at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) has successfully engineered high-purity gas conversion and purification systems for silane and germane. These two gases serve as critical feedstocks for the development of quantum information science and are vital to the domestic semiconductor industry.
Strengthening the Quantum Supply Chain
The project’s main goal is to provide a dependable domestic route for necessary supplies; it achieved a significant milestone 2026. To use device-compatible precursor gases directly in high-tech manufacturing, the US is currently striving to replace commercially available enriched starting chemicals. Under the strategic guidance of DOE’s Office of Isotope R&D and Production (IRP), this endeavor is managed.
Germane and silane are industrial workhorses rather than only lab curiosities. They are employed in the semiconductor industry to deposit silicon and germanium thin films, which are essential components of sophisticated computer chips. By guaranteeing a domestic supply of these high-purity gases, PNNL is assisting in protecting American research and development from the unpredictability of the global supply chain.

Innovative Separation Technologies
The application of improved thermal diffusion isotope separation (TDIS) technology lies at the core of this innovation. Even though PNNL has a history of creating TDIS systems for enriching gases like chlorine and argon, there were particular scientific challenges when switching to silane and germane.
To create systems that could safely and effectively handle these particular compounds, researchers pointed out that more research was necessary. Overcoming these obstacles was made possible by the lab’s proficiency with chemical separations. To satisfy the strict requirements needed for quantum technologies, where even minute impurities might disturb delicate quantum states, it is still necessary to further isotopically enrich these gases.
Precision and Safety in Engineering
Extreme accuracy is needed to preserve these materials’ integrity. Mike Powell, the project’s chief investigator and a chemical engineer, described the isotopic dilution of enhanced silicon as a difficult task. To preserve the initial feedstock isotopic purity all the way to the finished silane and germane products, Powell underlined that the group needed to “carefully design our systems and handling procedures.”
PNNL developed automated control systems and put strict safety procedures in place to minimize the inherent risks of working with these systems. These advanced controls keep an eye on hundreds of process variables in real time. The system immediately alerts operators if any conditions deviate from the precisely specified target levels, guaranteeing both the feedstock’s purity and the workers’ safety.

A Legacy of Scientific Discovery
This accomplishment is a part of PNNL’s larger goal to tackle issues related to energy resilience and national security. PNNL, which was established in 1965 and is run by Battelle, utilizes extensive knowledge in data science, biology, chemistry, and Earth sciences. The DOE’s Office of Science, which is the biggest sponsor of fundamental physical science research in the country, provides funding for the lab.
One aspect of the lab’s high-impact research portfolio is the work on silane and germane. A number of other significant projects were also revealed by PNNL in early 2026, such as the Genesis AI for Science program, which uses artificial intelligence to drive nuclear and biotechnology research. Six PNNL researchers were also recently honored with DOE Early Career Research Awards, underscoring the lab’s continued dedication to developing the next wave of scientific leaders.
Looking Ahead
The development of these purification systems successfully represents a sea change in the materials used in household quantum computing. The foundation for future computing technologies and autonomous systems is being laid by PNNL and DOE by bridging the gap between raw enriched chemicals and the high-purity gases needed for device manufacture.
The goal of ongoing research will continue to be improving these TDIS technologies and increasing the home supply of essential minerals and isotopes. This breakthrough is a significant step toward technological sovereignty and ongoing innovation in the global market for the U.S. semiconductor and quantum industries.
