Low-temperature Plasmas

Our low-temperature plasma research develops solutions for global challenges in high-tech manufacturing, environment, and medicine, through coupling advanced plasma sensing with simulations.

About the Research Area

Low-temperature plasmas operate in a highly non-equilibrium environment, where synergies between physical and chemical interactions drive unique processes. These technologies enable large area surface manipulation at an atomic and molecular scale for material fabrication in for example nano-electronics production. Tailoring the multi reactive species environment enables applications in areas such as medicine, agriculture, and energy storage. We collaborate closely with industrial partners to maximise the impact of our discoveries.
