The Leibniz Institute of Surface Engineering (IOM) is a non-profit organization and member of the Leibniz Association. Combining our expertise in science and engineering, we research, develop, and use beam-based methods to fabricate and process surfaces and materials with ions, electrons, photons, and plasmas. Our scientific knowledge serves the public interest and benefits society in forward-looking application fields such as optics, semiconductors, energy, biomedicine, and water management. The IOM thus contributes to the technological sovereignty and sustainable development of Europe.
