Structural and electrical properties of ZnO:Co thin films prepared by pulsed laser deposition

Nadir F.Habubi, Ali A.Yousif, Adawiya J.Haidar


The present paper is based on the study of polycrystalline ZnO:Co thin films deposited on glass substrates by pulsed laser deposition (PLD) technique using pulsed Nd-YAGlaser with wavelength (ë=532 nm),duration (7ns) and energy flounce (1.4 J/cm2) with different doping percentage (1 wt.%, 3 wt.% and 5 wt.%). The X-Ray diffraction patterns of the films showed that the ZnO films and ZnO:Co films exhibit hexagonal wurtzite crystal structure and high crystalline quality. Through the electrical properties: the dc electrical conductivity at a temperature range (27-300) ºC for ZnO:Co filmswere studied to confirmthat these films have two activation energies. Hall effect is studied to estimate the type of carriers, from the result we deduced that the ZnO:Co thin films are n-type. Seebeck measurements are used to obtain the thermoelectric power as a function of temperature.
