Electron Microscopy and Spectroscopy Laboratory

The Electron Microscopy and Spectroscopy Laboratory (EMSL) at the Institute of Nanotechnology (INT) at the Karlsruhe Institute of Technology (KIT) focuses on structural and compositional characterization at the atomic to nanometer scale, providing a direct bridge between synthesis/processing and properties/functionalities of materials for target oriented materials research and development.

The microscopy team in April 2019: a multidisciplinary group of researchers combining physicists, chemists and a geologist to cover the various application areas of electron microscopy (from left to right: Lakshmi Sravani Mantha, Wu Wang, Andrey Mazilkin, Vanessa Wollersen, Vinga Szabo, Ou Jin, Sabine Schlabach, Kai Wang, Christian Kübel, Di Wang, Torsten Scherer, Saleh Gorji, Leyi Chen, Ankush Kashiwar, Xiaohui Huang, Arshpreet Singh, Xiaoke Mu, Shyam Kumar Neelekandhan.
