    CONDUCTION STUDIES ON EUROPIUM OXIDE THIN FILMS
    (Wiley‐VCH Verlag/Physica Status Solidi (a), 135 (1), 207-214, 1993-01-16) Meena P; Balasubramanian C; Narayandass K; Mangalaraj D
    Conduction studies are carried out on Eu2O3 thin film capacitors. From the ac conduction studies the dielectric constant is found to decrease with increase of frequency (< 1 MHz), but at very high frequency (> 1 MHz) it is found to increase. The ac conductance is found to be proportional to f at low frequencies, whereas a square‐law dependence is observed at higher frequencies. The activation energy decreases with increase of frequency and increases with increase of temperature. The dc conduction studies reveal a space‐charge limited conduction in this film. The density of free electrons, the density of trapped electrons, and the mobility of free electrons at different temperatures are calculated and the results are discussed.

    STRUCTURE, AGING, ANNEALING, AND DIELECTRIC PROPERTIES OF EUROPIUM OXIDE THIN FILMS
    (Wiley/Physica Status Solidi (a), K97-K100, 1991) Meena P; Balasubramanian C; Narayandass K; Mangalaraj D
    Since very few reports are available on europium oxide (Eu2O3) thin films, further investigations on structure, aging, and annealing of Eu2O3 films are necessary. Hence the present study deals with the structure, aging, annealing, and dielectric properties of Eu2O3 thin films formed by vacuum evaporation.
