dc.description.abstract | The infrared photo-induced spectra of the isotope-substituted stoichiometric La 2CuO 4 samples were studied at T=20 K. Measured spectra were analyzed within the small polaron hopping theory. A small, but detectable shift of the effective phonon frequency on the substitution 16O to 18O is found for the high-energy surface carrier associated band (~4000 cm -1) and has a value of α O = 0.3 ±0.2. The low-energy band (~1500 cm -1) originating from the bulk carriers doesn't show any difference within experimental error which is fully in agreement with theory predictions. The isotope shifts of the optically active oxygen-related phonon modes are described well by the harmonic approximation. © EDP Sciences/Società Italiana di Fisica/Springer-Verlag 2006. | |
