In scanning probe microscopy (SPM) images of surfaces are created by moving a tip across the surface. Research in SPM aims to find suitable tips and physical interaction mechanisms which uncover specific surface properties. An important and proven method for mapping the magnetic order of ferromagnetic surfaces is magnetic force microscopy based on the magnetic dipole interaction ...

In vielen Bereichen der Industrie, v. a. der Halbleiterindustrie, werden zur Prozesskontrolle Vakuum- und Partialdruckmessgeräte eingesetzt. Für die in-situ Kalibrierung und zur Überwachung im Hoch- und Ultrahochvakuumbereich kommen Ionisationsvakuummeter zum Einsatz. Bei ihnen werden mithilfe schneller Elektronen Gasmoleküle ionisiert und der resultierende...

Fourier transform infrared (FTIR) spectroscopy is a powerful technique in analytical chemistry. Typically, spatially distributed spectra of the substance of interest are registered simultaneously using FTIR spectrometers equipped with array detectors. Scanning methods such as near-field FTIR spectroscopy are a promising alternative providing higher...
