Thickness Dependent X-Ray and Raman Studies of PrMnO3 Thin Films

Aditi Chaturvedi and V. G. Sathe
Abstract—Raman spectra of PrMnO3 thin films deposited on lattice mismatched substrate (LaAlO3) show a pronounced dependence on the film thickness and also on the degree of lattice mismatch. PrMnO3 thin films were deposited by pulsed laser deposition on LaAlO3 substrate, on this substrate the films experience in-plane compressive and therefore out-of-plane tensile strain. The gradual release of strain on increasing the film thickness is observed by the values of out-of-plane lattice parameters calculated by (002) reflection of films. A systematic trend in the Raman modes on increasing the thickness was also observed in the Raman spectra. All the Raman modes showed hardening on decreasing the thickness. This is attributed to the effect of strain gradually decreases on increasing the thickness of the films. Raman modes also seem to be sensitive to the lattice distortion in the thinner films.

Index Terms—Jahn-teller distortion, manganite thin films, pulsed laser deposition, raman spectroscopy.
