Karel Mašek received his PhD at Charles University, Faculty of Mathematics and Physics, Prague, Czech Republic in 1994. From 2004 he is working as Assistant Professor at Department of Surface and Plasma Science, Surface Physics Group in Faculty of Mathematics and Physics, Charles University in Prague. From 2017 he is a member of evaluation panel of Grant Agency of the Czech Republic.

The research activities can be divided into several topics:

  • Preparation and characterization of oxides in form of epitaxial clusters, low-dimensional self-organized structures and continuous epitaxial, these layers are then used as substrate for other deposit to form model systems for further investigation of their chemical properties.
  • Epitaxial nanoparticles on oxides – investigation of the growth, structure and chemical properties of oriented ultra-thin metallic layers representing model catalysts for investigation of basic research in heterogeneous catalysis and gas sensing, investigation of metal-substrate interaction effects, bimetallic nanoparticles.
  • Chemical reactivity of model catalysts – interaction of simple gas molecules with the surface of model catalysts, measurements performed in Material Science Beamline (MSB) at Syncrotrone Elettra in Trieste, Italy – soft X-ray photoelectron spectroscopy.

Diagnostic methods: Structure and morphology – reflection high-energy electron diffraction (RHEED) and low energy electron diffraction (LEED), scanning electron microscope (SEM), atomic force microscope (AFM) and transmission electron microscope (TEM, HRTEM). Chemical composition and stoichiometry – electron spectroscopy (XPS, AES), photoelectron spectroscopy induced by synchrotron radiation (SRPES) including resonance photoelectron spectroscopy, secondary ion mass spectroscopy (SIMS), NAP-XPS near ambient pressure XPS.

From 2003 Karel Mašek is president of the Czech Vacuum Society. He was a chairman of two Joint Vacuum Conferences in 2006 (JVC 11 in Prague) and 2018 (JVC 17 in Olomouc). He was also a member of organizing committee of International Vacuum Congress IVC 19 in Paris 2013 and European Conference on Surface Science ECOSS 22 in Prague, 2003.
