The La0.7Ca0.3MnO3 thin film shows a metal-insulator transition at temperature around 150 K, about 100 K lower than that of the polycrystalline sample. It is found that the activation barrier in the thin film is lower than that in the bulk sample. The FIR reflectance of the thin film exhibits a new mode which is not present in the bulk sample. We propose that the new mode is the corresponding surface bending mode.
