We show that the intensities of the local electric field in metal-dielectric granular films may exhibit giant fluctuations in the optical and infrared range when the dissipation in metallic grains is low. It is found that these fluctuations are highly correlated in space. We introduce a new...

(Bi0.92Ce0.08)2Ti2O7 thin films have been successfully prepared on P-type Si(100) substrates by a chemical solution decomposition method. The structural properties of the films were studied by X-ray diffraction. The phase stability of Bi2Ti2O7 was improved after Ce ions were doped. The...
