Epitaxy Laboratory

Molecular beam epitaxy (MBE) and metal-organic chemical vapor deposition (MOCVD) is used for fabrication of epitaxially grown Nitride materials for optical, electronic and magnetic applications as well as for basic research.

The laboratory is equipped for development and supply of optically active and magnetic materials on substrates up to 4 inch diameter. State of the art in-situ characterization tools provide high reliability and reproducibility of sample properties.

A wide range of in-situ and ex-situ characterization tools are available. A range of analyzes can be performed in the analysis chamber connected to the MBEs by UHV transfer. Analysis can be done after growth or on any externally introduced sample.
