Innovative Measurement Techniques in Surface Science

We describe four new experimental techniques advanced during the last decade in the authors’ laboratory. The techniques include photon scanning tunneling microscopy; aberration‐corrected low‐energy electron microscopy in combination with photoelectron emission microscopy, microcalorimetry, and electron‐spin resonance spectroscopy. It is demonstrated how those techniques may be applied to solve fundamental problems in surface science with growing demands to tackle complex nanoscopic systems, and, in particular in catalysis science, which, without the availability of those techniques, would be difficult if not impossible to address.
