    Abstract: Thin films of undoped and (Al, N) dual doped CdO were prepared on glass substrate at substrate temperature 350 ºC by spray pyrolysis method. The films are characterized by XRD, AFM, Optical and electrical properties. The films are highly poly crystalline and found to be cubic. AFM images show the surface properties of the film. It increases with i... Show More

    Abstract: Electron doped Ca1-xSbx MnO3 (X = 0 to 0.4) compound when prepared by high temperature solid state reaction, exhibits orthorhombic distorted perovskite structure. A systematic, continuous doping increases the metal – insulator transition temperature to above the room temperature (≈431 to 469 K); due to the mismatch of ionic radii in A site rising a...
