Description:

Low energy electron microscope (LEEM) is one of the instruments of the UHV-Cluster, which combines preparation and in-situ analysis by several complementary methods for the characterization of surfaces and thin films. The LEEM instrument utilizes low energy, elastically backscattered electrons to image surfaces with high spatial and temporal resolution. Advantages of LEEM over other surface imaging techniques are real-time imaging capability and existing several unique contrast mechanisms for image formation. LEEM is a powerful tool for studying the dynamic and static properties of surfaces and thin films, phase transitions, reactions, structure and morphology, and more.
