Pulsed laser photothermal displacement spectroscopy for surface studies

  • 82 Accesses

  • 44 Citations


The feasibility of pulsed laser photothermal displacement spectroscopy for surface studies is demonstrated. With this method transient heating phenomena can be investigated. The technique provides a real-time, non-contact and non-destructive probe of the surface temperature and can be used to study thermal properties and their changes, e.g. during pulsed laser annealing. Possible applications also include investigations of thin films and adsorbates in ultrahigh vacuum as well as in other environments.
