WebHow AFM Works. An AFM cantilever with a protruding ultra-sharp tip is raster scanned over the sample, which makes either intermittent or constant contact with the surface. The tip interacts with the sample, experiencing repulsive or attractive inter-atomic forces. A laser beam is reflected off the back of the cantilever onto a detector.
WebKelvin probe microscopy or KPFM is one member of a suite of electrical characterization methods available in scanning probe microscopy to map the surface potential or work function of samples. KPFM provides … WebFigure 2: The basic setup of an ellipsometer. Any ellipsometric sample characterization comprises at least two steps: In a first step, the ellipsometer measures the sample-induced change of polarization, which can be cast into two real numbers per probing photon energy. These are the so-called ellipsometric parameters Δ (“Delta”) and Ψ ...
