Core facility (CF)

Short Description

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.
Attached to the NanoESCA PEEM, a sample preparation chamber offers the cleaning and coating of sample surfaces under ultrahigh vacuum (UHV) conditions with a transfer system into the NanoESCA chamber without breaking the vacuum. Together, the two items NanoESCA Lab (Forschungsinfrastruktur ID 4511) and „Probenpräparationskammer plus –positioniersystem“ form the core facility „Photoemissions-Elektronenmikroskopie an Nanomaterialien“ (ID 4098). Details about the rules, responsibilities, and fees for using the core facility are available on request.

Methods & Expertise for Research Infrastructure

Initiators of the core facility are Prof. Dr. Wolfgang E. Ernst (Technische Universität Graz) und Prof. Dr. Martin Sterrer (Karl-Franzens Universität Graz). Ernst's expertise lies in the preparation and investigation of molecules and clusters with various techniques like laser spectroscopy, ionization, and particle scattering. Sterrer is expert for the preparation of nanoparticles on thin films, photoemission tomography, and the investigation of charge transfer processes.
