HIGHLIGHTS
- who: Walter Dickmann and colleagues from the , Braunschweig, Germany have published the paper: Key signal contributions in photothermal deflection spectroscopy, in the Journal: (JOURNAL)
- what: The authors report on key signal contributions in photothermal deflection spectroscopy (PDS) of semiconductors at photon energies below the bandgap energy and show how to extract the actual absorption properties from the measurement data. The authors demonstrate that these effects result in an additional deflection contribution that substantially depends on the distance of the photodetector from the readout point. B. Investigation of thermal expansion Analogously to the theoretical analysis of . . .
