Department of Precision Surfaces

Research and development of the department of Precision Surfaces of the IOM Leipzig focuses on the fabrication and modification of surfaces and thin films of various materials. The techniques used are ion- and laser beam- as well as plasma-based. The aim is to create surfaces and thin films that are useful in specialized applications. Apart from the required setups for the modification of materials, employees of the IOM can also resort to a vast number of appliances for the analysis of structure, topography and composition as well as the determination of mechanical, optical or electrical properties of surfaces and thin films.  

Apart from working on topics in the field of basic research the employees are also involved in various projects of technology and development transfer, especially to companies from optical industries, microelectronics and mechanical engineering.
 

Research and Development Foci of the Department of Precision Surfaces:

The focus is on the development of special beam tools, in particular plasma and ion beam sources, which support or enable a unique approach to surface modification including shaping, smoothing, structuring, layer deposition and functionalization.
