Photoemission electron microscopy

Photoemission electron microscopy (PEEM) visualizes the local variation of electrons emitted from a surface with high spatial resolution. We employ various light sources to generate photoelectrons ranging from Hg and He discharge lamps to nanosecond and femtosecond Ti:Sapphire lasers in order to explore the properties of materials at the nanoscale. The NanoESCA microscope in our laboratory is equiped with a special double hemispherical energy filter (EF), allowing for photoelectron spectroscopy with spatial resolution below 100 nm and k-space microscopy. Examples of our current research encompass the investigation of plasmonic nanostructures and nanoparticles as well as quantum materials.
