The physical principles of the new method for the determination elastic and thermal parameters of the solid were made. Possibility of application of this method for studying composites and polymer materials was demonstrated. Semiconductors structures have been studied by means of combined photothermoacoustic and photoelectric microscopy. Product Description popup.authors popup.nrat_date 2020-04-02 Close
